How to unscrew the bolt or nut with torn edges

During repair, surprises are inevitable. The equipment can bring, apparent durable detail - break in the most unnecessary location, and bolts and nuts resist unscrewing. And then the repair is stretched, take away over time, nerves and money.

Now online you can find a variety of video with a guide to carry out any repair work. They say, on the basis of video from the Internet, you can build a house from scratch and a car to go through the screw.

But with such a huge number of tips and recommendations, it is difficult to choose the right action for you. In this article we will try to collect all the available experience and systematize it for ease of use.

Bolt with torn faces

Now we will deal How to how to unscrew the bolt with torn edges . As a rule, the reasons for this misfortune lies in that:

  • Details that kept the bolt turned out to be displaced in an unnatural way. This leads to its clamping and spoilement.
  • The bolt itself, when twisted, was strongly tightened.
  • The tool to which it was delayed was not the size and used primary means (screwdrivers or chisels are often lined in the keys of a larger in the absence of suitable small).

Before unscrewed the torn bolt or the nut, you need to spend some preparation. This will allow you to spend less time and effort, and sometimes saving expensive equipment.

Sequencing

  • Cove the connection with a liquid that will help unscrewing. Such a liquid can be used by the famous WD-40, brake fluid or kerosene. Do not hurry, give fluids to make your business. As practice shows, thirty minutes, and then it is possible to boldly leave the item alone.
  • Take any healthy tool and lightly, not much, do hardly by hardware from all available parties. Your goal, in this case, do not run a bolt as a golf ball, and just slightly break it on the place of its attachment. During this event, there is a danger of damaging the thread, so that measure the strength and ship.
  • If there is an opportunity and space, try heating the bolt. For this, gas burner will fit. Ensure that there are no flammable liquids and items near the workplace. Ensure before warming up that in case of an unforeseen situation, you have where to retreat. Do not warm up the part of open fire in closed rooms. It is better to open the gate or move the bolt to the air. Failed in this way rust and fat will turn into ashes, and stop preventing the bolt rejunction.

However, it often happens that it is exactly the screw, to which it does not come with a burner or an upset tool. In this particular case, it is necessary with a grinder or any girlish tool like a chisel make a deep cut in the preserved hat . He will become the hook that will allow you to pull out the entire bolt.

Now you can, clinging for this protrusion, try unscrewing the unsuitable screw. Hear a screwdriver with a screwdriver, and performing light blows on its handle of hammers toward unscrewing (not clockwise), slowly turn the bolt.

Bolt under the hexagon

The axis faces are convenient and for twisting, and for unscrewing. Clear and even they give reliable stop for the key. If the bolt is suitable for hand and the appropriate size, at first it can be comfortable to twist with a hand, reaching it later using the tool. However, there are cases of cases where due to excessive operation of the screw itself, or large load loads, The edges are torn And fasteners remain hanging in articulation. It is inconvenient to take him, he slips out of the hands and tools. Let's consider several options for solving this problem, with the relevant ways to eliminate.

  • Make on the head bolk tank in any available way. However, when performing this notch there is one important point. The walls of this notch must be vertical, without slope. Otherwise, the tool that you will then leave to the excavation will simply slip through the Hat. And in this case there is a big danger to damage not only tools, but also the hands of the master.
  • Apply special so-called extractors for screws with torn faces. Extractors have a thread, sliced ​​in the direction, which is exactly opposite to the thread of the bolt itself. Thus, when the hole is drilled in the bolt and an extractor is inserted, it is fixed in the bolt tightly and does not turn around when the bolt is unscrewed by the pliers.
  • Use the reverse left rotation drill and drill with reverses. The idea is to having having a regular drill hole in the fastener, shove the left drill to it and turn the bolt to unscrew the bolt on the reverse.
  • Find a suitable star Torx. The ideal asterisk should not pass by the slots in the hole of the hexagon, but not to be too big for him. Torx asterisk will cut the bolt cap with its slots, locking tightly on the hat. Now it is possible to unscrew the screw in a strong movement. Carefully, because in this case there is a big danger of ripping the slots from the Torx asterisk.

Screw with a hole under the hexagon can be unscrewed in the following way:

  • You need to take a feet and make them size under the hex key. Having made such a propyl, you will significantly save, because you can use this fastener in the future more than once.
  • Make a bowl on a hat with a grinder or any other in a convenient way, for example, with a metal hacksaw. And use a flat screwdriver, resting in her handle, as in the shoulder of rotation.
  • It can also be used to unscrew the screw one from the size of TORX sprockets.

For bolts-connecting rods made of steel, there are only two ways:

  1. Take advantage of the extractor. A competently selected extractor and your careful actions will help not only unscrew the screw, but also do it without significant tool damage.
  2. Call for help electric welding. Electric welding can be attached to the torn fastener any hexagon element that you no longer need. Thus welded, it will become a new screw for a screw. It will be comfortable to rest and unscrew. But unfortunately, this method can only be used and exclusively for parts made of steel. With bolts from other materials, this convenient way, unfortunately, cannot be applied.

Bolt-star

You can unscrew a similar bolt as well as unscrew the nut with torn faces. The main ways of unscrewing the unsuitable bolts and nuts were disassembled very detailed by us earlier, and now we can summarize all the ways that are suitable for such a screw. So, If your bolt-star has frustrated the faces:

  • The easiest way to use the extractor. Excellent proven tool will not let and this time. Perform a hole in the foot of the fastener, lock there the suitable extractor and cautious movements to unscrew the stuck bolt. As we see from this article, a set of extractors of various diameters - a thing really necessary in the farm, if you regularly do similar assemblies and disassembly.
  • Use the gas key. This adjustable key tightly takes a bolt, and you can extract it into several turns. This method is good because you do not need to buy a separate tool. There is a similar adjustment key in almost every home.
  • Focus on a bolt hat. In the presence of sufficient space around the bolk. Do you wrote onto his hat with a grinder or hacksaw. In this notch, you will be able to double the screwdriver or the chisel and turn the bolt, hitting the hammer or other tool comfortable at its free end.

We looked at the options for the release of bolts and nuts that are available for use to any home master. Of course, the methods used on professional workshops or in car services remained beyond the discussion. However, the equipment is constantly used, which at home you will be useful once or twice. And it is worth a lot of money. Professionals are used to release bolts with torn edges:

  1. Wheel.
  2. Spilingter.
  3. Specialized extractors.

However, if such situations arise with you no more than once a year, then there is no particular sense to acquire special tools.

How to unscrew the torn bolts, nuts, screws

Sooner or later, any owner faces the situation when the nut, bolt or self-tapping screws do not want to get out. There are several reasons: Metal of low quality, violation of technology (paled screws), rust, time, too much efforts attached when tightening the connection. However, unscrew the bolt with torn edges, the linked nut, the rusted connection can be. In this article, let's talk about how to do it.

Unscrew the torn bolts and nuts

The "jams" edges on bolts or nuts are not so rare. Excessive efforts that are attached when tightening, and then when unscrewed, often lead to the fact that the boundary between the edges of the bolt is erased. If the bolt is not unscrewed - the usual keys in this case are powerless - they are simply scrolled, and the fasteners remain in place.

Torn or linked faces on the nut or bolt do not give it to unscrew

To unscrew the disruptive bolts and nuts there are several ways:

    Using a gas adjustable key. Due to the ribbed sponges, adjustable the degree of "tightening" and a sufficiently large lever, the adjustable key helps in most cases. This tool is frequent, so the first thing to do if you need to unscrew fasteners with the linked thread - try this method.

Gas (pipe) key - the best tool for unscrewing nuts

How to work with extractor

If under the bolt there is a plastic or rubber gasket, it is removed and once again try one of the proposed methods. If you cannot unscrew the bolt with torn faces with all these methods, one cannot be left, one thing remains: cutting off / cutting the hat and drill a pin.

Rusted nut

Another problem that is familiar to motorists (and not only) is a rusted nut and / or carving. In this case, you should not make the heroic effort to unscrew the fasteners. You simply "lie" the edges and to the boiled thread will add another problem. If after a pair of attempts, it is impossible to unscrew, alternately try the following methods:

  • Spanner tapping a bolt. There is a possibility that the rust will crack and the nut will be able to unscrew.
  • Pour the connection of kerosene and wait. He is a rust jack, after which the rusted nut will be unscrewed easier. But with this operation, it is impossible to smoke, turn on the welding, be located near the open fire.

Not the most elegant, but effective decision

Furizers for torn nuts

Still with rust you can fight with lubrication. Try pouring the place of the fluid universal lubricant (there is in WD40 springs). Waving a couple of hours, we try to work the key. I did not work - we try other ways alternately.

Self-torn Slots (asterisk)

If the shifted screws were twisted a couple of times / twisted, their verges lose their sharpness, the screwdriver scrolls, and the screw itself remains on the spot. If he "sits" in wood, plaster, chipboard or other similar, not too hard materials, you can put a thin rubber for a screwdriver (for example, for hair). Due to the strength of the elasticity, it is achieved a more dense fit to the remaining faces, which helps to shift the self-sighs. The remaining methods are more "traumatic":

    Cut the grooves inside the "jammed" funnel using a flat screwdriver, unscrew. This method is sufficiently dangerous: if the walls of the "funnels" are too thin, there is a possibility that the screw head will simply turn away from the effort. There will be only a screw that will not get unscrewed.

This is how difficult to unscrew

Unscrew the screws with torn faces (cross)

The remains of the bolt or hairpins without a hat can be unscrewed like this: cut the left thread in the remaining body, drop by glue "moment", screw the left tap, leave for an hour. On the main thread drip oil and also leave for an hour. When glue grabbing, unscrew. If the wood stuck the remnants of screw screws in the wood, it is easier to close this hole and set to install another fastener.

Methods of twisting bolt and screw with torn edges

By performing repair work, sometimes the question arises: how to unscrew the bolt or screw with torn edges. This task has several solutions, knowing that almost any hardware can be promoted. Even in the case when you stopped and threw the head or broke the hairpin, there are ways and tools that allow you to twist the fasteners.

Preparatory events

Any problem is best prevented than solving. Therefore, if you attached a sufficient effort, and the fastener did not move from the place, you do not need to continue until you damage it completely. Better do the following:

  1. First you need to remove the rust layer and other contaminants. If the threaded part protrudes over the fastened parts, clean it with a metal brush.
  2. Take the hammer and overtake the head. Blows must be quite strong. Nothing terrible if you make small dents on the metal, but it is impossible to allow the curvature of the fastener itself. This procedure helps to disrupt the integrity of oxides, so the positive effect will be only at the initial stage, when the head is pressed to the part. After you have broken a bolt from a place, it is not recommended to knock on it, since the likelihood is that you damage the threads than complicate the position even more.
  3. Very good results gives heating the place of attachment. Everything you need is to heat the fastener and wait when it cools. In this case, some of the substances burn out, the rust is destroyed, and the bolt is twisted with a smaller force. Heating should be strong. It can be carried out by a soldering lamp, a gas burner or acetylene cutter. In all cases, an open flame is used, so first make sure that you do not damage the surrounding elements. Do not forget about compliance with safety regulations!
  4. Lubricate a habitat of any easy-to-eat fluid. This can be a special composition of type WD 40, kerosene or brake fluid. Their feature is that they penetrate all the pores and cracks, lubricate the thread, and some destroy rust. For a positive effect, some time must go. Usually recommend waiting for about an hour and start working. In difficult cases, it will be necessary to wait 10-12 hours.

The above actions will not be superfluous and in the case when you decide how to unscrew the bolt with torn edges.

Ways to unscrew the bolt

Below are the most effective ways to unscrew the damaged bolts and screws.

With spoiled edges

Determining how to unscrew the bolt with torn edges, you need to consider whether there is access to it, location, and which tool you can use. Based on these factors You can apply one of the ways:

  1. The use of chisel. The method is suitable for large bolts to which there are free access. All you need is a hammer and chisel. The chisel is applied on the tangent of the head and apply sharp blows along it. The way is simple, but it infrequently allows you to achieve the desired result. It should only be applied when there is no other tool at hand.
  2. If there is free access to the location of the fastener, you can use a universal stop-key key. This tool allows reliably to hold even a round head. If you use small stopping keys of the "Cobra" type, in which there are sharp notches on the working surfaces, then you can unscrew the smallest bolts. Such a tool can rescue in many cases, but it should be new. In a worn tool, notches can no longer provide reliable grip with metal, and the key will slip.
  3. If the faces are not damaged, they can help the heads for the cape. For these purposes, the profile of a cape key must be with 12 faces (inside the head of the stars, not a hexagon). References are made as follows. Choose the head one size is less than the size of the bolt, and with the help of the hammer, it is turned onto the torn faces, then unscrewed in the usual way.
  4. This method is to use the metal hacksaws, with the help of which the bolt on the head is made under a flat screeching. The depth of the cut should not be more than 75% of the height of the bolt head, with greater depth one of the halves can break.
  5. If your disposal has a file or bulgaria, then you can restore the face of a smaller key. If there is a horn key, cut the hexagon optionally, it is enough to make two parallel faces.
  6. If you can use welding at the location of the attachment, it will greatly facilitate the task. In this case, you can put on the head to put the nut of a suitable diameter and weld them together, and then use the usual keys.

In difficult cases, in order to achieve the desired result, you need to combine several ways. Therefore, first rate the setting, decide how to unscrew the bolt, and only then proceed to work.

With torn head

Very often, sacrificing old threaded connections, you can not only damage the verge of the bolt, but also to rip the head. Then the question arises: how to unscrew the torn bolt. If you disconnect the parts, and the torn bolt protrudes from the body of the part, then you can use all of the above methods.

And how to unscrew the bolt with the torn head, if the body of the bolt does not protrude from the part? There are several options for solving this task.

  1. It is best to apply a special tool - extractor. The extractor is made of a cylindrical metal rod, at one end of which the conical carving of the opposite cutting is located, and on the other - the shank of the square section. In order for it to be used, in the center of the bolt, you need to drill a hole. Hole diameter - 2-3 mm less than the diameter of the thread. After that, you need to take a suitable extractor and slight blow to score it into the hole. Rotating extractor for the shank, unscrew the remains of the bolt.
  2. If there is a tap with left-hand thread, you can successfully apply it as an extractor. The only difference is that the hole diameter should be as to cut the thread. The exact value can be found in the respective tables.
  3. If you unscrew the chip still, you can try to delete it in this way. In the bolt drill a hole of the maximum possible diameter, trying not to damage the threaded connection. Then take the corresponding tap and cut into the thread hole. During this process, the thread is cleared and the residues of the bolt are removed.

It is quite difficult to drill the hole. And if you damaged the threaded connection, then it is possible to correct the position only by replenishing the hole and cutting the thread of the larger diameter.

The cut pin is not different from the bolt with the torn head, and therefore the methods of its twisting are the same.

Damage to thread

There are cases when the thread of the fastener is damaged. In this case, the methis is freely scrolling, but it does not work out from the threaded connection. To solve this problem, it is necessary to lift the bolt. It is possible to do this with a screwdriver or another similar tool that is dyed under the head and lifts it with an effort. When the bolt is strengthened, it is starting to rotate in the direction of twisting. This is done until the hardware is completely extracted. If the hole of the threaded connection is through, then you can push from the reverse side using any tool suitable for this.

If you have a similar problem with the nut, then proceed in the same way. Hardware with damaged carvings are subject to replacement, so if there is access, the nut can be cut off with a grinder or knock down the chisel.

Under the stall and hexagon

Recently, fasteners with heads under the stall, hexagon and more exotic forms are increasingly used. If the faces on such a fastener are damaged, and you need to unscrew it, you can act by analogy with conventional bolts with the only difference that you need to use a tool with an appropriate face form.

Removing the screw

Many hassle deliver screws with torn faces. Unscrew such screws not easy, but there are several ways to solve this task. In order for them to be easier to turn out, you need to make the same preparatory activities as for bolts.

In the simplest case, when the screw protrudes over the surface, you can try to grasp it with pliers, laying or other similar tool and soak it in such a way. But most often grabbed nothing. Then you can try the following methods:

  1. Sometimes it helps the use of fine rubber, for example, from a balloon. A piece of such rubber is put on top of the screw and unscrew, pressing the scum through it. This allows you to strengthen friction and avoid slipping overlap.
  2. The screw with a figured head can be removed under a flat screeching, peeling the groke.
  3. In order to solve the problem of cleavage slipping, you can apply glue based on cyanoacryl, such adhesive will quickly dry and high quality fastens metal surfaces. The procedure is simple: the screw and diverter are degreased, glue is applied to the screw head and pressed scolding to it, observing the alignment. To accelerate the grasp of glue, you can sprinkle with soda. Wait for the complete hardening of glue and try unscrewing the screw.

In order to further avoid such problems, update all the threaded connections with layers or tags before assembly. Replace the entire fastening with damage. Be sure to lubricate the thread and fastening as a whole. It is best for these purposes to use graphite lubricant.

How to unscrew the bolt with torn edges

Basically, each repair is not smooth, but with the emergence of small problems, the elimination of which has to spend strength and time. What to do in the situation when it is necessary to disassemble the design, and the bolt rusted or is spoiled, we will look at it further.

At home, it is not for each wizard there is a necessary equipment at hand, but with this problem you can cope with infirred means.

How to unscrew the torn bolt?

Main methods:

  1. Clean the surface with a metal brush and treated with diesel or kerosene. Trying to unscrew the nut with a cape. Although there is no one hundred percent warranty that it will unscrew.
  2. With the help of a chisel and the hammer do strikes towards unscrewing. This method is not suitable for a small nut.
  3. Gas key with a powerful clamp a good tool in this situation. They can easily capture even round items, but harder in hard-to-reach places. The longer the handle, the easier it is to carry out operations on unscrewing.
  4. When the fastener with a large size and unscrew it is difficult, then you can apply a metal coating using welding equipment and prepare the necessary turnkey form with a file.
  5. They drink a drill hole inside the body of the fastening element, they make a rod of a r-shaped rod, which will serve as a handle, and remove.

When there is enough space for the use of a divorce key or passatate - it is good, and what to do in other situations?

How to unscrew the head bolt under the hexagon or asterisk

For recess element Apply gas key With the compression of the part, they cut the bacal on the hat on a hat and unscrew the screwdriver, the extractor of the appropriate size, the special tools (wrench, spit-lying), to acquire which is beneficial only if there are often faced problems with such problems.

Pick up the TORX asterisk in size (it should not be big and the slots go into the hole under the hexagon). It is introduced tightly into the hat and the bolt is unscrewed, to avoid a breakdown of the sprinkle. When climbing sprockets with holes in the center, they are laid out, so it is not recommended to use them.

In any building and auto shop Sale sets of extractors . Externally, this device has a form of a metal rod with cone carvings on the left side and faceted base with the right. With their help, unscrew nuts with torn edges. To do this, the hole is dried strictly in the center of the bolt, the extractor of the desired size is clogged and unscrewed with pliers. It is done simply and quickly, because the cutting extractor is the opposite.

Drill with reverses - an indispensable thing. Make a thin drill hole at the bolt. Take the left rotation drill with a smaller diameter and in the invertive rotation mode dried a damaged bolt.

If the head of the bolt broke

In this case, you need to be patient and choose the appropriate option.

Three ways:

  1. The hole is drilled by 3 cm less than the diameter of the bolt and the tap is screwed into it with the left thread as long as the broken part starts to get out.
  2. If part of the bolt acts, it can be done on it with the help of a grinder under the spline screwdriver and start twisting.
  3. Based on the hole in which the extractor is screwed up counterclockwise. Then the damaged element is then retained.

The process takes a few minutes, but meet Covership products Under the hexagon, the edges of which are easily broken. Torx suitable sizes will help to cope with such a problem.

How to drill a broken bolt

Professionals advise to use a short diameter drill and ensure that it does not lean when working. When buying, you need to focus on the country of the manufacturer and cost. High-quality drills cannot cost cheap, sharpened specially and made of hardened steel.

Split nuts and bolts produce slowly and consistently In this case, it is impossible to hurry in this case, otherwise then there will be unforeseen problems and loss of time on their elimination. For example, many auto machines rush to unscrew rusty bolts that break. It is lost a lot of time to eliminate errors. Therefore, it is necessary to immediately plan the course of action. How to cope with rusty bolts, discuss further.

How to unscrew the bolt

Often the repair of the car is complicated due to the presence of corrosion and oxidation of fastening elements. For example, at the plant when assembling the master did not proceed with lubricant with lubricants, and water got into operation there. As a result, the bolt sucked, it would seem that it was, but with such a nuisance you can cope with several ways.

Unscrew the rusted bolt or nut tapping

When tapping from a bolt Rust and scatter , so unscrew it becomes easier. The operation is carried out by a hammer, turning the special tool in order to create a torque. With caution, as you can damage the product and you will have to drill it. After removing the fastening element, it is brushed from rust and treated with graphite lubrication. In the presence of clothes dust on the connection.

With the help of solvents

In the arsenal of any experienced motorist there is always a set of liquids to combat rust and other raid. Basically use WD-40 with a good penetrating ability to microloors, the cost of which starts from 100 rubles . Along with him, the brake fluid, white spirit, kerosene, coca-cola apply. In contrast to WD-40, other liquids are weaker, and it is better to pour them into the container and put an accusable connection to it for a larger effect.

If the bolt is bought on the front rack, the solvent substance can be accurately pour into a "glass". The main thing is not to damage the gums on the racks, otherwise you will have to change them.

Wash the cloth with any means, wind the nut and leave for a while. Then they cut the bolt to destroy the softened rust and begin to unscrew.

Thermal method

When the solvent does not cope with the task, you can try exposure to fire and cold . In any large car or shopping store, a gas burner is sold, it is used with it a bolt to bright orange. Then cooled with machine oil and try to weaken it. With an unsuccessful attempt, the process is repeated anew.

This method does not always help, and with a close location with a paint coating, the fuel tank is very dangerous. When working with a gas burner, you need to follow the rules of fire safety and not use it if there is no fire extinguisher at hand.

Apply sprays for freezing products to save the bolt for further use. But use such reagents mostly professionals, since in household conditions it business cost and unprofitable .

How to unscrew the linked bolt

When scrolling the bolt, it is pushed with a nail-made and pulled out to the maximum possible height, leave in the stretch and gradually twisted the key. When there is no nail, you can use a screwdriver. A small bolt is extracted with nail bearings. If he does not give in right away, then rotate it, clapping against a clockwise arrow with an effort up.

Use the tap , Insert it until it stops. If it is not at hand, a screwdriver with a cone-shaped edge is suitable, which is carefully clogged to the stop and try to unscrew.

So that such situations are not repeated, they need to be processed with graphite lubricant before twisting the bolts. But the solidol or lithol is not used for this purpose, because they are used for rubbing parts, and the bolted compounds after lubrication are encountered.

How to unscrew the bolt with torn edges

Used daily equipment has designs connected by fasteners. Repair or maintenance requires dismantling certain nodes and aggregates. The fastening bolts over time can be corrupted or torn. Unscrew the knot with torn edges is not easy, due to the location, poor availability. Often, problems are created by jamming faces and corrosion processes that are generated during operation.

Conacts of the extraction of bolts with torn thread

To remove a spoiled bolt or nut, you need to hold a number of preparatory procedures. Created conditions will help with subsequent work, will preserve the assedes of the units.

  1. Apply a liquid to the surrounding surfaces that contributes to less friction of threaded compounds. The assortment of household stores has a lot of special means, but it is possible to use brake fluid or kerosene.
  2. Reducing the fastening resistance is achieved by several accurate impacts with a hammer. It is necessary to control the force, otherwise there is a risk of breaking the mount, thereby slow down the extraction process.

How to determine what tools it is possible to unscrew the bolt with torn edges. Before work, it is necessary to correctly select a tool, evaluate the state of torn fasteners. There are several basic methods for extracting:

  • In the absence of other elements around the zone, it is possible to use the gas key. The tool is used on the part with the size of the part, too large the key to unscrew the small thoring item will not work.
  • Pick the head with edges suitable for cure, the size of the head must match the design.

How to unscrew the broken bolt

With an insufficient seizure area for a pipe key, attempts to use the tool in this situation are practically useless. It is necessary to use a file, for the manufacture of faces on a torn product of a smaller diameter. After successful processing, the key or the head is selected, you need a diameter, smoothly unscrewed the resulting element.

Revealing of the torn bolt

Using the hammer together with the chisel can make it easier for labor, it is necessary to make a notch and accurate blows to reveal the tool. This method is considered effective, as the shock force acts on the right side. As soon as it is visually determined that the process has moved from the place, you can use a suitable cape key or head.

If there is a welding machine under hand, you need to screw the nut on the hat, then with a sharp movement it is possible to unscrew the torn part. In cases where the nuts nut is not possible because of the lack of space, a piece of metal is boiled for further faces.

As the element of the connection with the torn edges will be twisted, experienced masters will tell, some simply begin to drill without losing time. An effective way is to eliminate the washer between the bolt and the clamping area. The hammer is applied to the chisel installed on the nut.

How to unscrew the head bolt under the hexagon or asterisk

In the automotive industry, other equipment often use bolts under the hexagonal tool. How to unscrew the tornbeach, which is breaking the face:

  • Make a horizontal bowl with a grinder or a file on a hat. To unscrew the torn screw, at this case, a strong screwdriver is used.
  • Using a special TORX sprocket, which is driven into a hat. The nozzle is selected in size, slightly torn the hats, for a durable connection between the walls.
  • A set of extractors that may be purchased in a shopping store. Before using the extractor, the hole drill is drilled at the base of the bolt, then the extractor is introduced, the screw is extracted with a pliers or a special clamp.
  • The use of drill with left rotation, slightly smaller on the diameter of the hole. The tool is performed in reverse mode, with this method it is possible to ruin the thread.

How to unscrew the bolt with torn edges manually

Torn nuts are getting out more difficult, since when working there is a chance of damage to the thread. The easiest way is the use of chemicals, surface processing is cleaned and processed by a means for 15 minutes. When torn edges, apply the key or head is impossible. In such cases, the chisel is used, which is destroyed by the bulk of the nut, is then removed and replaced with a new nut.

How to remove the bolt if the head broke

The broken head of the design can deliver a lot of trouble when working. How to act with such a difficult situation without resorting to the use of a serious tool. With small sizes of the element, it is possible to do with a grinder, the deepening of which will allow you to use a screwdriver with sharp edges. To perform more complex works, you need an extractor, drill and sweep. The base of the threaded connection is dried exactly in the middle, after the manufacture of the hole, the instrument is screwed down the clockwise.

When performing consecutive actions, unscrew the damaged element of the structure will not be difficult for those who are first faced with this problem. It is necessary to competently assess the situation, use a good quality tool for productive results.

How to drill a broken bolt

For work used drill from high-quality material. The size must be selected in accordance with the torn edges, the diameter of the drill should not be greater than the hole. High-quality drill is characterized by an increased price, but its use eliminates rapid wear and the possibility of breakage in the work process.

Use the tool is not rush, before performing the task, competently assess the situation. It is necessary to monitor the position of the instrument in the process of operation, drill is made strictly in the center, without deviations in different directions.

How to unscrew the bolt

Maintenance of a car or other equipment occurs during an aggressive environment. The compound falls moisture, which acts on harm metal, creating conditions for the formation of corrosion. As a result, the fasteners in the connections are accumulated, unscrew the parts in such situations seems impracticable task. Some wizards do not use the means and preparatory work, which leads to a breakdown of a hat or a thread of the bolt.

Revealing the accurate bolt

Each situation requires a separate approach, the type of damage to both attachments and threads before performing the task is performed. There are several basic ways to unscrew the accurate bolt.

Unscrew the rusted bolt or nut tapping

One of the effective ways is tapping a hammer along a torn design hat.

Rusty accurate bolt.

A hammer is used as a pair with a precipitant key, which is attached to the unscrewing force. The operation must be made with marginal caution, as it is possible to spoil the face of the cap, which will become even more problem. Typically, rusted bolts are replaced with new ones, in the absence of such an opportunity, contamination and corrosion traces should be removed, lubricate with special lubricant threads.

With the help of solvents

There are many solvents of different categories on sale. A variety of use of such elements like White spirit, fuel fuel and even Coca-Cola. The most effective chemical means for unscrewing the torn elements is WD-40 and varieties. The liquid is processed by the structure of the structure, if the hole is through, it is necessary to pour the opposite part.

To accelerate the process, it is necessary to cut the rag with a chemical solution, process the connection, catchy to remove the upper words of rust.

Thermal method

More serious corrosion deposits are not always processed by a chemical method. Such compounds are heated with a gas burner to a split state, sharply cooled with water. With thermal exposure, the metal is expanding, then it is sharply narrowed, which makes it possible to exit sediments through a threaded connection.

Removing a bolt with a gas burner

The use of the burner is not always rational, as it is possible to damage the paintwork and close-based nodes. It is safe to work with caution near the fuel system, since the gasoline pairs can ignore and lead to irreversible consequences.

How to unscrew the linked bolt

When working with compounds, there are situations when the thread scrolls into the landing opening. In this case, a nail-holder is used, it is inserted between the cap and the case, then unscrewed the tensioned bolt. When working with small-diameter fasteners, it is possible to use a screwdriver as a lever, the hat is unscrewed with nipples or rashes with a small force.

After removing a spoiled bolt, you need to check the hole for the integrity of the thread, to install the new connection. In case of poor thread status, a tap is used. The tool is inserted into the hole until it stops, the new thread is cut further. If the state of the hole is not suitable for a new compound, the diameter is increased by using a larger tap. After work it is possible to choose the fastening of the size as the performed hole.

In situations with the lined glare hats, the above methods will help. There are many types of connections and holes. To perform work, you need to have some skills prepared by the tool. Each situation requires a separate approach and a certain preparation, only in such conditions, it is possible to achieve the result.

How to unscrew the bolt with torn edges. Extraction methods

Almost every equipment is assembled with fasteners. With long-term operation, they may be unusable. With the emerging repair situations, there is a need to remove fasteners and very often mechanics are faced by the situation when the product rusted or became unusable. Most often it concerns bolts and nuts. They may have the lines of the face, the thread that has come into disrepair, the bolts are molded by heads. How to unscrew the bolt with torn edges or torn head? Consider several similar situations, each of them has its own specifics.

Removing a bolt with torn faces

It is not always possible to see the necessary equipment for such works, especially at home. You can use the applying tools that will be almost every host.

1st way. You will need a hammer and chisel. This is the easiest way, but not always effective. The chisel is installed at an angle to the product, then strikes with a hammer toward unscrewing. For small bolts, this method, alas, is not suitable.

3rd way. In such a situation, the famous gas key will come to the rescue. This device has a fairly powerful clamp, which allows you to capture even round items. This method and disadvantages have it, its use is impossible in hard-to-reach places of structures.

Removing a bolt with a broken head

The situation becomes more complicated if the head fell off the head. How to unscrew the broken bolt? Consider possible options for solving the problem.

1st way. The main condition for performing is the protruding part of the broken bolt. With the help of a grinder, it runs the rubber screwdriver. Now you can start removing.

2nd way . To do this, you will need a tap with left-hand thread. Drive up a hole with a diameter by 2-3 cm. Less bolt. It is starting to screw in it, this action is performed until the broken part persists and does not begin to get out.

3rd way. With core and hammer. This method is similar to the above the action describing how to unscrew the bolt with torn faces, in the first paragraph.

Dismantling bolt - Application of specialized equipment

To solve this problem, a series of devices are successfully applied, which use very often car repairmen. Consider the most common options for extracting with special equipment:

    Set of extractors. Serve the hole in the remainder of the bolt. We drive the hammer extractor of the required diameter, in the set there is dimension from M6 to M16. Screw the sleeve and with the help of a clay key remove a broken bolt.

Twisting knotted nut

There are also several ways to this.

1st way. Previously compound is cleaned with a brush and wetted by kerosene or Special WD-40 solution. It is withstanding the time interval of 10-15 minutes. Now you can proceed to unscrew the nut using a cape or horn key. Before the revealing process, you can catch a hammer connection, the blows should be not too strong.

2nd way. If the connection is in the free access area, unscrew the nut with the torn edges, using a vise or an adjustable key. It is clamped between sponges of the instrument and turns first a little along the thread, and then in the opposite direction.

3rd way. If you failed to move the nut from the spot the ways presented, then you should move to extreme measures. The chisel and the hammer are made on the surface on the surface, after which the fasteners are versed. Application in the future removed in this way the nut is impossible.

Dismantling scrolling fastening

Sometimes there are situations when the bolt is scrolled in the threaded hole, how to unscrew it, consider in more detail. First you need to pose a product with a nail and pull it out to the maximum possible height. Leaving the connection in the stretch, we gradually unscrew the bolt. If not in the presence of a nail, create a lever with a screwdriver. If the bolt is small, you can remove it with nipples. The head is clamped and reinted upwards. If the bolt has not pulled out right away, then start rotating the heads of the head against a clockwise, without weakening the effort up.

Sooner or later we are all faced with this problem. I will tell you how to solve this problem and how to prevent it in the future. Now in order
How guaranteed to unscrew the bolt or nut with torn edges. 7 folk versions

I will give several ways to solve this problem.

1. The easiest option Do not immediately take for heavy artillery. We try the harmless way. Clean the jammed connection with a metal brush. We drip some kerosene or diesel fuel (wait for 15-30 minutes) if you're lucky, then you can unscrew the bolt or nut. If there is no alas. We try to simply cut the ill-fated object (not too much!).

2. Brutal option We use a gas key for these purposes. Due to the fact that it has a powerful clamp and a big lever, it can well cope with this task.

One thing, it will not always help if the place is inaccessible.

3. Technological way When the gas key does not help, Bulgarian comes to the rescue.

Very traumatic tool, it is advisable to use it only a professional or a person who has already worked with him, newcomers are better not to use this method

It is necessary to cut new facets, only a bit size is smaller than the bolt or nut. Enough four faces. Next, using the head or a cape, we unscrew the bolt.

Horn Key Troat is not recommended

You can restore the face with a file, though this process is longer.

4. Folk option We take the chisel and the folk instrument, the hammer. True, they will be more useful for nuts (in the case of bolts, success is not guaranteed). With accurate blows on a tangential spoiled nut on either side. Caps are unscrewed towards the direction against the rotation of the clockwise. Usually it is possible to move fasteners from a dead point.

6. We use welding We weld the new nut (or rod) to the spoiled head or torn nut, and then unscrew it. It is this way that is ideal for all small items, small things, for example, torn screws on the computer cover, laptop, mobile phones. Only instead of welding here you need to take superciles.

7. Final option When not one of the ways did not help in solving the problem, one output remains, extreme. In a helping of chisel and hammer (several times, hitting the hammer as the chisel attached to the right place) to be cut into parts, and only then proceed to the disassembly of the whole compound. True, then you have to change not only a spoiled nut, but also a bolt (if he still remained whole). But the problem will be solved.

Various fasteners (bolts, screws, screws) are widely used in construction, car repair. With a long operation of the connection site, it is necessary to regularly maintain: twisted, pull, periodically disassemble and collect again.

Torn verge of bolt

Often the master faces the problem of breaking the threads on the bolts. In such a situation, you have to apply non-standard techniques to extract fasteners, because it will not get it in the usual way.

The reasons for breaking the thread

Trouble with fasteners, as a rule, are found with poor-quality maintenance of products. Screws often do not have an anti-corrosion coating, and over time, their surface rusts, the thread move is violated. As a result, the twisting the usual screwdriver becomes difficult.

Bolt with damaged thread
Bolt with damaged thread

Threaded problems can cause:

  • Drop-down - disruption of the integrity of the fastener under the influence of high temperatures;
  • Low quality of the product itself - in this case, the deformation can happen during the screwing of the bolt;
  • Natural wear - occurs when it is too long exploited or excessively high loads;
  • Apply an inappropriate tool for screwing and unscrewing.

How to unscrew the bolt with torn thread

To pull out the spoiled fastener, you can use different methods - ranging from the simplest, manual, and ending with the use of power tools. Sometimes the rounded bolt is tightly stuck inside the product, so you have to use several different techniques.

Tapping hammer

This method works well on the wheeled bolts, so it is popular among auto mechanics. Blows cause vibration, because of which the bolts are better out of the connection site.

Out of wheel bolt

Take the knocker and the end head strictly in the size of the fastener, set the entire design and hit the hammer several times at the turn of the twist. Between the blows turn the tool. Skip and rust are quickly destroyed, the bolt turns.

Important! This method is not suitable for small fasteners and hard-to-reach places.

Applying solvent

White spirit and other solvents are often used to get rid of the problem fastener, as well as special compositions (for example, WD-40 in the form of an aerosol). They work especially well if the problem of smoothed thread occurred due to the strong corrosion of the metal.

Liquid for unscrewing nuts

The solvent quickly penetrates the micropores and gaps, dissolves dirt, soot, rust. If there are no specified tools in the presence, kerosene or brake fluid can be used.

Pliers or adjustable key

The fastener is clamped with sharp cloth and begin to twist them in the thread direction, as if the usual key. Often this is enough to remove the bolt, as high-quality ticks immediately adhere to even smooth metal.

You can act with a filter key. The nut is clamped only with the tips of the sponges, after well tighten the screw on the working part of the element. The hammer is stuck the key to the bolt and they are also sharply hitting the handle to the side to disrupt the nut.

Using a confront key

Important! It is necessary to follow, so that the key does not slip, otherwise the carving will break even stronger.

Thermal impact

From high temperatures, the metal is quickly released from rust and scale, after which the defective bolt comes out well from the hole. The easiest way to use the gas burner.

Heating of the threaded burner
Heating of the threaded burner

The fire is directed directly to the bolt, heams about 3 minutes, and then unscrew it with a horn key or a screwdriver. You can not apply this method for compounds located near the wires and next to the easily flammable substances.

Docted for screwdriver (bits)

If the fastener was drunk, you can do it. For this purpose, they take the metal hacksaw, in the center of the bolt neatly put the furrow under the size of a screwdriver or bits.

Docted under a screwdriver

The latter is used if the bolt strongly rustled, and it will not be able to unscrew it manually. This technique is well suited for fasteners of any size, although when they are located in hard-to-reach places with propyl, problems will arise.

Bulgarian

This method of unscrewing rusty bolts is similar to the previous one, only the separation of the opening under the bit is performed using a grinder. Also, Bulgarian is perfectly suitable if fasteners with torn thread have additional nutritional problems. The latter is cut with a metal disk, then it is performed for a breakdown, and the intelligence element is removed by the screwdriver.

Extractor

This device is intended directly for bolts with rounded edges and resembles a pin with screw threads. If the bolt's hat is wide enough, in it drill a hole with a thin drill, and then the hole is completed, exactly suitable under the diameter of the extractor, a thicker drill. Then the tool is driven by a hammer blow into the fastening element, clamp the head of the radiance and rotate in the direction of unscrewing the bolt.

Welding

Sometimes the old fastener not only rusted and rounded, but also lost the nuts as a result of mechanical damage, an inaccier attempt to remove. The best output will be the use of welding, with which you can build a new nut and unscrew the bolt.

In this way:

  1. Prepare a new nut (the size of the product must be greater than the old nut).
  2. Weld the item to the fastening element.
  3. We are convinced that the new nut is firmly sits on the pin.
  4. Take a suitable screwdriver or insert a bit in the screwdriver, unscrew the fasteners.

Modern end heads

Such tools tend to use professionals, since their cost is higher than the price of standard fixtures. Similar end heads, keys can work even with rounded bolts, as they have a special design and come into contact only with the edges and walls of fasteners.

It is important to purchase a tool made of durable, solid chrome metal and not save. Otherwise, it can be deformed with a significant twisting effort.

Set of end heads for damaged bolts
Set of end heads for damaged bolts

In order not to know the problems with twisting bolts, it is better to take prevention measures in advance: to properly install fasteners, to replace it in time, to work as a suitable tool. It will save time, strength and money and will save from solving the emergence of trouble.

The verge of bolts over time curls, which is especially happening with rushing and rusted bolts that cannot be unscrewed. Trying to do this, people often themselves turn the edges themselves, leading to disrepair not only the heads of the bolts, but also the keys that tried to unscrew them.

There are several ways to unscrew almost any bolt, regardless of the degree of rusting and the status of the faces. Using these ways, you can unscrew any bolts, even those whose head is doring, and a piece of bolt remained in the thread. About these ways and talk today.

Five ways to unscrew the bolt with torn faces

Need

What may be needed to unscrew any bolt or nut:
  • a set of keys of different design solutions;
  • liquid key or WD-40;
  • Drill with drills;
  • Extractors
  • shock screwdriver;
  • wrench;
  • Electric welding machine;

If you have it all, you can unscrew almost everything!

Five ways to unscrew the bolt with torn faces

Traditional ways:

  • Conventional keys. If your key turns, try replacing it. Instead of wrench keys, you can use cash. Among the capes there are also options - multifaceted key and hexagon. And you can also try tubular heads that can be used with threads with volatile corners to bring out uncomfortable place. Depending on the quality of the key and the status of the bolt, you can experiment to understand which key allows you to unscrew the problem nut or bolt.

  • Wait. It is necessary to warm up the bolt or nuts in cases where he rusted so much that even the liquid key does not take it and the auxiliary lever does not help. It is possible to warm up using the usual gas burner. Five ways to unscrew the bolt with torn faces

If traditional ways do not help, then it's time to purchase a special tool with which you can unscrew all anything!

5 best ways to unscrew the bolt or nut!

1. Special extractors heads. The internal parts of these heads have spiral swirling grooves, and the bone-mold hole itself. In order to unscrew the bolt using such an extended tractor, you need to score the end key to the bolt head and scroll! The taper allows you to clamp the bolt head, and the spiral grooves pick up the face and unscrew the bolt. Then the bolt itself will have to knock out the key.

4. Impact methods. Here you can apply a classic set of hammer and chisel and special screwdrivers with a solid rod adapted to strike.

Five ways to unscrew the bolt with torn faces

First, the chisel or screwdriver is knocked out, and then the bolt is unscrewed on this notch. The way you can simplify if you use a special impact tool. When you hit the back of such a jacking screwdriver, its head produces a rotational blow to the bolt. You can still use a wrench to simplify the work, and you can also weld the nut to the spoiled bolt head, if there is open access to the reserved node.

We are looking for reasons, warn the accident, give hope!

Inmit and rearrange - the same bad if it comes to repairing the car. And in particular - about the metric threaded fasteners, which is found on the hub, wheels, the receiving pipe and other details. It seems that you can avoid the common problem of the distributed fasteners, if you contact a reliable car service. In fact, there is no difference: what is in the official dealer auto center, that in the garage workshop - a fastener can break everywhere. But not all of the wine car service: over time, with regular maintenance or repair, fasteners wear out.

Sorvannyj-Bolt.

Forums are filled with despair of motorists: "Strong the face of nuts! Help unscrew! ". A hundreds of "experts" are answered to the request. Whose advice is good, and whose will exacerbate the situation? It is not easy to figure out. In addition, you can spend a lot of strength and time to try all ways. It is possible that the right tool, which is spoken of forums, you do not have. And if you buy it, it is not a fact that the method will work.

What to do with the rapid edges of the fastener?

How to be if a rounded bolt sorted in a thread?

Is there a right approach to rusty nuts without risk of damage to the tool arsenal?

We have answers, how to work with problem fasteners. We tried to collect information in such a way that you find out your situation and the right way was selected from the first time. We will share Lifehaki, which will help to be divided with deformed bolts and nuts. There are techniques and for small, and for large connections. We recommend to read the article to the end: we have prepared something for dessert. And now let's try!

At the footsteps of experienced masters. We study proven methods

Punch hammer

This method works well on wheel bolts. Thread does not endure vibrations, so the blow helps to rip the bolts.

How to use?

It will take the knob and the end head under the size of the fastener. After installing the design to the bolt, you need to take a hammer and hit the twist several times on the spot. In parallel with strikes, the tool rotate. As a rule, if the bolt is not very rusty and rusty, he immediately moves and easily dismissed.

Palets-Vniz.Not suitable for hard-to-reach places and fasteners of small size.

Split nut

When the nut does not take anything or maintain it meaninglessly, the method is underway using force. Its essence is to expand fasteners in diameter and deform its threads. The method can be applied in hard-to-reach places.

Gajkolom.

How to use?

To knock off the nut from the thread, you will need a chisel with a hammer, a pneumherbilo or a special tool - Gaikol. The chisel is applied to one of the faces of the nut and hit the hammer on it. As a result, a deep notch is formed on the mounting element. The same notch will help to make pneummabilo or Gaikol. The fastener thread is deformed, the nut is expanding in diameter, and therefore it is easily removed with a key or end head with a ratchet.

Palets-Vniz.Not applicable for bolts.

Palets-Vniz.It will not be possible to save the nut the whole.

With tick or adjustable key

There are sharp cloves that capture the most rounded fastener at the cobra ticks. Well with this is coping with an adjustable key.

How to use?

It is necessary to clamp the fastening element with ticks and twist in the direction of thread, as a regular key. As soon as you put a tool on a bolt or nut, you will feel a reliable metal tap with metal. If no new pliers, you quickly cope with the task.

Perestavnye-kleschi.

An adjustable key is somewhat different. The nut is pressed not completely, but only the tips of the sponge, then the screw is tightly tightened on the working part. After that, the key is stuffed onto the fastening element, carefully tapping on the handle with a hammer. The same hammer with a sharp movement is hit on the handle aside and break off the nut. It is worth trying if there is easy access to fasteners!

Palets-Vniz.There is a risk even stronger strain the face if the key will slip.

Palets-Vniz.With dimensional instruments, do not bring to bottlenecks.

Pressing head

If the verge of nuts are set, an end head with a 12-graded profile can help. Choose a nozzle to size less than the diameter of the bolt cap.

How to use?

Hammer Press the head on the walled fastener. The nozzle should be one with a nut. Take the ratchet and in the usual way to unscrew the fastener.

Palets-Vniz.The end head will deteriorate.

Lampa.Tip!

If you decide to apply this method, it will be better to buy an inexpensive nozzle separately.

Cutting new faces

A fairly simple way for which only a file will be needed. It is to cut down new facets on the nut. It is not necessary to diligently drink all six faces. To capture the key will be enough two or three.

How to use?

Clean the metal so that there are no rust or scale on the fastener. Create a new face with a file, and then the key to capture the bolt. If the thread inside the connection does not rustle, then it should be easily unscrewed.

Palets-Vniz.If the fastener slow down a lot from one side or from the inside, the face will not be written.

Palets-Vniz.If the thread of the hairpins is damaged, only cutting the faces will not help unscrew the bolt.

Propil for screwdriver or bits

One of the favorite methods of masters who are constantly faced with fasteners with rates. But it only applies to bolts. If it is impossible to grab the key over the fastener, it will help to unscrew the flat screwdriver or bit. To do this, you need to do.

Propil

How to use?

For the cut, you will need a hacksaw of metal or Bulgarian. In the middle of the bolt, the groove is neatly peasants, suitable for the size of the bits. When it was ready, you can start unscrewed.

Lampa.Tip!

For rusty fasteners, we recommend using bits that are planted on a ratchet or wrench adapter. It is unlikely to be handled manually with a conventional screwdriver if the connection is forkid.

This method is suitable for both small and large bolts.

Palets-Vniz.Bulgarian and hacksaw will not get to hard-to-reach places.

Palets-Vniz.Not suitable for nuts.

Drill plus extractor

Another method is to drill the bolt hats. Let's say right away, it does not always work. Masters to it are also ambiguous. But it is applied to the method not only to the walled glands of the bolt, but also to broken hairpins.

Sverlo-Ekstraktor.

How to use?

You will need an extractor - this is a special device for bolts with rounded edges. It is a pin with screw thread. Under it is drilled the cap of the fastener. First, it makes a subtle drill to outline the future hole and make a recess. Then take tooling this size so that the extractor is tightly inserted. When the hole is ready, the device is driven by a sharp blow of the hammer in the well.

Ekstraktor.

The sawmill clamp the extractor head and begin to rotate towards the bolt off. You must feel the maximum tightening - it will mean that the torque turned stuck or broken fasteners.

Palets-Vniz.Not suitable for nuts.

Palets-Vniz.Requires large labor costs.

Palets-Vniz.Often does not work.

Welding

If previous ways did not work, try welding. The essence is to join the old fastener of a new nut, which will easily capture the key or end head.

How to use?

Take a larger diameter nut than a bolt hat or an old nut. Using the welding machine, weld a new element to the old. This will provide the most reliable connection - the nut will not be able to break, as if it were simply naked with a hammer. After taking the key or the end head suitable for a new fastener and unscrew.

Palets-Vniz.Requires special welding skills.

Palets-Vniz.Not suitable for hard-to-reach places next to the electrocomponents.

Have launched cases?

  1. Bolt with raw edges hats and rusty stud.
  2. Rusty nut with deformed graces.

In these situations, use the "Wa.". So the people call the WD-40 spray-lubrication. However, there are other manufacturers of composition with a similar action. The agent penetrates the connection and destroys rust. It is necessary to spray the composition on the bolt or nut, wait 5 - 10 minutes so that it will affect, and then unscrew the item.

Another way is to heat the gas burner. From the effects of high temperatures, iron expands: fasteners increase in diameter, and it can be turned out without an effort. If, for example, the nut rusted on the receiving pipe, this method will have to be. Install the gas burner to the cylinder and direct its flame directly on fasteners. Heat for 3 to 4 minutes. Then take the usual horn key and unscrew the bolt or nut. This method is not suitable for large fasteners and to connections that are near the wires.

Each method has advantages and disadvantages. But none of them cannot be called universal. Anyway, there is a risk of damaging the item in the car, even more to run the verge of fasteners, get injured, spend a lot of time and forces for useless actions. Even if you have already chosen a suitable way, do not hurry to try! As you remember, we promised something for dessert. About the super-modern method of combating rapid grain fasteners will be further.

See, buy, quickly unscrew the problem fastener!

This method is superior to the head described above. Why? It turns out to unscrew the deformed bolts and nuts much easier, cleaner, safer and faster.

Not so long ago there were tools that are suitable for working with fasteners whose faces are deformed. This means that the end heads and keys are capable of capturing almost round caps.

Face heads of the new generation

Modern nozzles have a special profile. They come into contact not with angles of nuts and bolts, but with their faces and walls. There is a uniform distribution of effort across the entire outer area of ​​the element. This allows you to unscrew fasteners with rounded 85% edges, and most importantly - warns the stratification.

Tortsevye-Golovki.

Of great importance is the material of manufacturing end heads. Previously, users complained about soft metal - nozzles did not withstand the loads, and the profile was deformed. High-quality end heads are made of chromovanadium steel, which passes hardening. Therefore, modern tools are reliable, durable and withstand multiple unscrewing. So, the inforce nozzle withstood 2755 unscrewed and remained in good condition.

It is important, what ratchet you will work in a pair with the end head. The number of teeth in the mechanism affects the angle of rotation and the ability to work in hard-to-reach places. For example, Inforce recently came out a ratchet with 72 teeth, which made it possible to exceed DIN standard relative to torque by 40%. It can be used in conjunction with the impact tool due to cast design.

Treschotka-72zuba.

Manufacturers try to make sets of tools as functional as possible, so they are equipped with extension cords, gates, magnetic heads, cardan hinges, keys and many others. With these fixtures easier to unscrew the deep, hard-to-reach, located at an angle of fasteners. Why look in the past and use Dedov methods when there are specially created tools?

Keys with improved form of zea

Recently, many novelties of keys have appeared: combined, horn, cape, hinged and finishing. They are also able to cope with waste fasteners by metal hardness, which reaches 46 HRC. This allows the use of a hammer tool - the design of chromovadium steel will not work, and the metal is not deformed. CRV coating protects against corrosion and rust.

Gaechnye-Klyuchi2.

Modern tools at a price will stand slightly more than greikoloma, welding electrodes, lubricants or set of extractors. But the end heads and keys will be useful not only in problem situations, and will help in solving everyday standard tasks. And most importantly, with their help you can safely, easily and quickly unscrew fasteners with rates, even hard to access.

Warn the stratification, and not eliminate the consequences

To twist the bolt, at first glance, everyone will be able. Despite the simplicity of the operation, it is necessary to approach the matter with full responsibility. Especially when it concerns the car. Proper twisting is the key to your safety on the road. If it is bad to tighten the wheel bolt with "reboot", it can unscrew on the go and create the risk of an accident. It happens that fasteners enclosures in the hub and creates two problems: and does not hold the item, and does not get out so that you can put another. Why is this happening?

  1. The thread of the bolt is broken, and the edges on the hat are licking As a result of applying too much effort When screwing or unscrewing fasteners.
  2. Bolt or nut very old : Metal is simply rotted, and the edges rounded. Also, the hat could be covered with rust and rust.
  3. Work incorrect, unsuitable tool , and what is at hand.

Avoid problems with threaded connections will help, first of all, the correctly selected tool. It is very important to choose high-quality keys and heads. If we take on the principle "the cheaper, the better," you can run into the tools with a soft metal profile curved, which do not close with fasteners, and spoil its face.

It is better not to wait until the nuts do not do that inappropriate according to the satellite, the first tool. The keys and heads of the chromovanadium alloy with a special profile will help to forget about the problems of torn faces from compounds. You can make sure you look at the video.

Torn fasteners, at first glance, it seems a big problem. But now you know that the main thing is the right approach. Take on the note by Lifehaki users or work by professional tools is your choice. And we will help you choose the perfect set for your tasks and budget. We wish you good luck in a fight with raw bolts and nuts!

The car has many details connected with screws, bolts and screws. Situations occur quite often when the head of the bolt or the slot on the screw is linked, the screw. Therefore, the question of how to unscrew the bolt or screw with the linked faces is relevant for many motorists.

Why the edges of the screw, screw or bolt lick

The impression is called the stratification of the faces of the bolt or the slot to the screeper on the screw of the screw, screw or self-press. With such a problem, both a master and a beginner may face. When licked the faces at the bolt on it begins to slip the key and unscrew this item is not possible. Shlits on the head can be damaged from shlits and screws, it also leads to turning to turn off and cannot be unscrewed damaged fasteners.

The reasons why the shlits of the screw, screw or face near the bolt, nuts can be merged:

  • application of a worn tool;
  • incorrect use of a key or dumping;
  • poor-quality fastening element.

If during the unscrewing fastener the key or screwdriver slipped, you should not panic and you need to figure out for reason. Sometimes it is enough to change the scolding or the key so that the problem immediately decided.

Jumped bolt.

Mystery is called erasing faces or shlits

Methods of unscrewing bolts, screws, screws with linked edges

If the usual way it did not work out to unscrew the fasteners, which shoved the edges, you can use one of several proven options.

Gas key

This method is used when unscrewed bolts, since they are headed by a head for which you can grasp. For this:

  1. Clean the head of the bolt.
  2. Lubricate the connection of the kerosene or diesel fuel, the liquid of type WD-40 helps well, and leave for 15-20 minutes.
  3. Remove the bolt. Do this gas key. With it, it creates a lot of effort and it is possible to capture even a round head. Gas key

    With the help of a gas key, you can create a lot of effort and grab even a round head

The lack of such a method is that it is not always possible to get a gas key to the right bolt.

Cutting new faces

If a big bolt, then with the help of a grinder on it, you can cut new facets. It is enough to make them only 4 and with the help of a smaller key to unscrew the bolt. You can cut new facets on the bolt with a file, but it is more complicated longer. On the screw of the screw or screw, you can make a break with the help of a handwheel on metal or a grinder.

Application Bulgarian

On the screw of the screw or screw can be made a deeper incision for turning

Hammer and chisel or shock

This option is more suitable for linked nuts or sufficiently large screws. The chisel rests into the head of the fastener element and, hitting the hammer on it, gradually turn the screw or nut. Small screws or screws can be unscrewed by shocking and hammer. After weakening fastening, the work is performed by the usual scolder.

Shock screwdriver

Impact scaffolding can be unscrewed small screws or screws with linked slots

Harness or piece of rubber

In this case, a small part of a medical harness or a piece of dense rubber is used. The selected material is placed on top on the head of the screw or screw, after which they pressed the scolding and gradually turn it. The presence of rubber will help increase friction and solve the problem.

Application of Zhgut.

Harness laid between scolding and screwing screw or screw

Extractor

The extractor is a special tool that is used to unscrew the screws, bolts or screws with linked or broken heads.

Extractor

Extractor - tool for unscrewing screws, bolts or screws with linked or broken heads

The order of its application:

  1. With the help of a thin drill in the head make a small hole. In some cases, the extractor can simply score the screw slot into the muted slot.
  2. Select the extractor of the required diameter. Drive or screw it into the prepared hole. It depends on whether the usual or screw tool is applied.
  3. Unscrew the bolt. Application extractor

    The extractor is screwed into a damaged bolt, and then unscrew it with it.

Video: Out of the muted screw with the extractor

Normal or left-hand drill

On sale there is left-sided swelling with a rotation counterclockwise. They improve the centering of the tool and reduce the load on the drill, which gives higher performance and accuracy of drilling. By inserting such a tool into a drill, you can unscrew the screw or screw with the jammed head. If there is no left-sided drill, you can try driving stuck fasteners using usual. In this case, you need to take the drill, the diameter of which is less than the diameter of the bolt or screw. It is necessary to act carefully so that you do not have to cut the thread for a new fastener.

Reversing the bolt

The drill must have a diameter less than a problem bolt

Glue

To the head of the problem screw or screw with epoxy glue or glue called "Cold welding" fix the nut of the corresponding diameter. After the glue reliably attaches it, with the help of the key turns the nut and turn off the screw or shock with it.

Epoxy adhesive

With the help of glue to the linked head fix the nut, and then the screw is unscrewed with it

Welding

If there is a welding machine nearby, then a new nut on the head of the bolt or screw can be welded. After that it can be immediately unscrewed.

High welding

You can spend a new nut to a problem bolt or screw

Solder and soldering iron

If you need to unscrew a small screw or a screw, a soldering iron and solder are used:

  1. Preheated solder dripped on the head of the fastening element with linked edges.
  2. While the tin is not frozen, the scum in it is inserted and expect a few minutes. Applying soldering iron

    In the slot of the screw drip off the solder and insert holes

  3. Remove the problem screw and clean the sting of a shower from the solder.

How to prevent breaking faces

In order for such a problem, like torn faces of the bolt or the slot of the screw, the screw did not find you surprise, you need to stick to simple rules:

  • You only need to buy high-quality fasteners that have high strength and reliability;
  • During twisting and unscrewing screws or screws, it is impossible to slip screwdrivers in the slots. This leads to their erasure and unscrew this fastener will be difficult;
  • Always need to follow the state of the instrument. If you have a screwdriver or key jamming, then with their help it will be difficult to unscrew the screw, bolt or screw.

It is much easier to prevent the licking of the faces on bolts, screws and screws than to unscrew damaged fasteners.

Do not panic when such a problem appears as the muted head of the bolt or slot on the screw head, screw. There are many ways to solve it. It is necessary to adequately evaluate the situation that has arisen, and select one of the available options.

How to unscrew, disrupt, cut or unscrew the bolt with torn edges

We all faced a similar problem. The convulsive movements of the screwdriver in attempts to remove the screw with a damaged slot only aggravate the situation. The reasons why notching could be different, ranging from rush / hurry and ending with "gifts", which is so kindly provided by the repairmen, which unsuccessfully tried to finish the planned!

The removal of the torn fastener requires the manifestation of a little resourcefulness, but the goal is noble and it is worth implementing it.

Before you 5 reliable methods for removing torn screws, we will start with the most gentle method and move to a method that can be called "cheap and angry".

The method you choose will depend on your situation and the degree of importance of removing non-donutible fasteners.

Will not allow screws to destroy our day. Unscrew them!

Step 1: Rubber Tape (Rubber)

How to unscrew, disrupt, cut or unscrew the bolt with torn edges

Sometimes everything that happens is needed to unscrew the stubborn screw - it is a little zoom in the area of ​​contact. Elastic gum will help keep the end of a screwdriver in a hat with a disturbed slot and prevent scrolling.

How to unscrew, disrupt, cut or unscrew the bolt with torn edges

You can take any gum, but the broad suitable is better. Since it provides the largest contact area between a hat and a screwdriver.

How to unscrew, disrupt, cut or unscrew the bolt with torn edges

Running an elastic rubber band on top of a screwdriver and pull quite strong enough so that it does not make it, then carefully install a screwdriver into the disturbed slot and slowly check it.

How to unscrew, disrupt, cut or unscrew the bolt with torn edges

If the slot is not completely "Ushatan" rubber tape to fill the space in those places where the notch is broken, and will provide the necessary friction, which will allow you to unscrew the screw.

Step 2: Click screw in the cartridge screwdriver

How to unscrew, disrupt, cut or unscrew the bolt with torn edges

If the screw is not completely recessed into the material, there are a good chance that you will find it into the cartridge of a drill / screwdriver and easily unscrew back.

How to unscrew, disrupt, cut or unscrew the bolt with torn edges

Open the clamping cartridge and placing it on top of the screw screws. Next, we drag the cartridge with your hand so that "cams" fasten securely on a screw. We install the screw switch / drill on the reverse and slowly unscrew it from the board.

How to unscrew, disrupt, cut or unscrew the bolt with torn edges

It works with any type of screws / screws / bolts, the size of the caps of which allows them to hold them in the clamping cartridge.

Step 3: Device for removing torn screws

How to unscrew, disrupt, cut or unscrew the bolt with torn edges

If you caught an extremely stubborn fastener, which does not want to get out, it's time to cause severe artillery.

Screw extractors have left-hand threads, and rear-sided screws.

How to unscrew, disrupt, cut or unscrew the bolt with torn edges

Extractors are of different sizes. It is necessary to choose the right size for screwing into a torn slot. We will install an extractor into a screwdriver clamping cartridge and reliably tighten the cartridge.

We set the drill switch to the reverse. Since the extractor has a backwater, it means that a drill with an extractor installed on the reverse will be brought into a hat. Continuing to drill in the opposite direction the extractor will start turning the screw, thereby twisting it from the board.

Step 4: Cut a new slot

  • Another way to unscrew the non-dusty fasteners is to apply a new notch on the hack of a torn screw.

Using engraver with a cut-off disk, we strive for a groove in the Hat of the experimental. After which a flat screwdriver is fastened.

Step 5: Cork Drill

If the screwdriver sits in the material on a decent depth, and there is no other option, as it can be removed ... The time has come from the discharge "cheap and angry". The drill remove the material around the fastener to the depth of the screwed cap.

Install the drill to the drill and place it from the top of the screw. Let's start cut into the wood, and after remove the resulting material. We repeat the procedure until it reaches the level below the level of the Hat.

  1. Delete sawdust and see if it will get to the screw to remove it to one of the methods listed above.

Step 6: Leave it alone?

  • Sometimes the screws are too drowning or as they say in the commoner "nozzle is not worth it."
  • If you do not have ideas, how to unscrew the hated screw, and you can bypass it, you may just just hide it with a piece of wood.

Step 7: Share your advice

Need / need - Progress Engine. I am confident that there is a significant number of more skilled ways to remove torn fasteners. Why not share them in x to the article?

That's all. Thanks for attention)

How to unscrew the bolt with a spoiled head

Reading time: 6 min.

Damage to fasteners can be called one of the most common problems during repairs. Such situations occur both when repairing vehicles and during the repair of any items in home everyday. How to unscrew the bolt with a damaged head, consider further.

How to unscrew, disrupt, cut or unscrew the bolt with torn edges

Preparation for the twisting bolts with torn edges or carvings

The main criterion for the correct handling of the technique is the neat dismantling of fasteners. It is better to prevent breakdown than eliminating the consequences.

When a significant effort was applied to unscrewing the bolt, and the fastener remained in a fixed state - it is not recommended to continue dismantling. The result of excessive efforts will be damaged hardware.

If the bolt broke - the repair will take much longer.

How to unscrew, disrupt, cut or unscrew the bolt with torn edges

Preparatory activities include several points:

  1. Remove rust and contamination layer. If the carving protrudes over the part, it should be cleaned with a metal brush.
  2. To obstruct the head of the bolt with a hammer. It is necessary to hit fastener. Blows are directed to the destruction of oxides, which are formed over time. The maximum effect from the blows will be only at the stage when the head of the bolt is still in pressed to the base. After a breakdown of fasteners, it is not necessary to knock on the place to not damage the thread. The main thing is to prevent the bolt curvature.
  3. An effective way to unscrew the bolt can be called the heating of the place of fixation. The task is to heat the fastener and give it to cool. At this stage, the rust begins to collapse, some substances burn out. Bolt after that it is much easier to unscrew. It is desirable to heat the fastener. To do this, you will need a soldering lamp, acetylene cutter or gas burner. In each case, it is necessary to adhere to safety, since it is an open fire.
  4. Lubricate the bolt to an easy liquid type. The most common means is the aerosol composition WD. The advantage of such a fund is that it quickly falls into all the cracks and applies to carvings. Pretty effective composition is considered to be brake fluid and kerosene. To achieve the desired effect, after applying the means to the place of attachment it must be left for some time. It will be enough for one hour, however, sometimes you have to leave the items and for 12 hours.

Mounting for microphones

Step by step instructions for twisting the bolt

The following techniques will help solve the problem of filtering fasteners with a different nature of damage.

With spoiled edges

How to unscrew, disrupt, cut or unscrew the bolt with torn edges

Experience experience will prompt , How to unscrew the bolts with torn edges. To do this, use several effective methods at once. The speed of operation affects the location of the fastener, the presence of the necessary tools and the availability of metis. It is recommended to use each of the following methods in turn until a complete dismantling of damaged hardware:

  • The use of acute chisel. This method is applicable only in the case when a large bolt broke. Weight argument will be access to fasteners. To remove the part with a broken face, you will need a chisel and hammer. To the head of the bolt on the tangent, you need to make a chisel and apply the hammer blows along it. This approach can be called the most simple. But such actions are not suitable in all cases.
  • More efficient is the method of applying a stop key. If there is free access to hardware, the universal key with a high probability will be able to disrupt the element from the scene. The principle of operation lies in the use of special notes, which are located on the working surface. The key securely clamps the head and allows you to unscrew the smallest bolts. Mandatory condition - the stopping key must be new.
  • The key key may also be an essential device. Heads for unscrewing bolts with torn edges quite often cope with the most complex cases. The key profile should consist of 12 faces, and inside - the jack is an asterisk. The head should be one size less than the bolt. The part is neatly put on fasteners with a hammer and begins the twisting of the methization.
  • Metal hacksaw. The device allows you to cut the recess for the further unscrewing of the metric flat screwdriver. At the same time, the depth should be 25% less than the height of the head of the metric.
  • With the help of a grinder or a file, you can make new faces for a smaller key size. Having a hornble key, you can make only 2 faces parallel to each other.
  • Spare option - use the welding machine. In this case, the bolt must be accepted an extra nut.

Damage to thread

How to unscrew, disrupt, cut or unscrew the bolt with torn edges

A common problem is damage to the thread. As a result, the bolt scrolls in the seating area and is not extracting out. There is a proven way how to unscrew the bolt with torn thread.

With a flat screwdriver, it is necessary to raise fasteners. To do this, the screwdriver is placed between the head of the metric and the base, after which the fastening element with an effort is raised upwards.

Then you need to start unscrewing until the moment of complete extraction from the landing place.

High-strength bolts

Experts also recommend push fasteners from the reverse side, provided that the hole is a cross-cutting sample. If there is no possibility to dismantle the nut because of the torn thread, this place is cut off with a grinder.

Under the asterisk and hexagon

How to unscrew, disrupt, cut or unscrew the bolt with torn edges

Much distribution received fasteners with heads under the asterisk, as well as a hexagon. Such hardware are reliable and easy to operate. However, such details may also fail.

If the faces are damaged, you need to act in the same way as in the case of simple bolts. The difference lies only that dismantling is performed using special keys with the faces of the characteristic shape - hexagon or asterisk.

Under the screwdriver

How to unscrew, disrupt, cut or unscrew the bolt with torn edges

With limited access, you can make a notch on the bolt. Chisel or Bulgarian comes to the rescue. Having done propyl, try to unscrew the hardware with a screwdriver.

If this method does not bring the desired result, the screwdriver is set at an angle and apply a hammer strike knob. Before unscrewed the torn bolts, it is recommended to apply a lubricating fluid.

The applied force should be directed counterclockwise.

Detailed video about ways to unscrew damaged bolts:

Procedure when unscrewing a bolt with a broken head

Threaded compounds become a real test when the bolt head is chosen as a result of applying force. If it turned out the details, the dismantling of the methis is not difficult. Much more time and effort will be required when the head breaks down, and the fastener will not speak out of the ground.

How to unscrew, disrupt, cut or unscrew the bolt with torn edges

The procedure includes the following items:

  • Use the appropriate size extractor. These tools are made from a cylindrical rod. One side of the metal blank contains conical threads of the opposite type of cutting. The second side is equipped with a shank with a square cross section. The use of the item is possible provided that the bolt is pre-selected. In this case, the diameter should be 3 mm less thread. Then it is necessary to choose an extractor and score a device into the finished hole. The twisting bolt with a torn head is made with a neat rotation of an extractor shank.
  • An excellent solution to the problem will be the use of a lever with left thread. The accuracy of the diameter should be observed, which must correspond to the value of the thread. The method consists in pre-drilling a new hole and cutting a new thread. The approach will be difficult for those who do not know how to unscrew the muted bolts. As a result, all parts of the broken bolt will be removed out.

How to unscrew the bolt

Repair of various elements of the body and main nodes of the car does not cost without solving the problem of corrosion, oxidation of bolts. As a rule, all fixing elements are carefully treated at the masters plants.

High-quality lubricant is present on the thread of all seats. With further repair, such formulations are not applied.

After entering the water to the surface of the thread, the connection is accumulated, and the scurrid bolts becomes too difficult to dismantle.

The masters use three effective methods for solving this problem. Select the appropriate option follows from the ability of the owner of the car.

Unscrew the rusted bolt or nut tapping

How to unscrew, disrupt, cut or unscrew the bolt with torn edges

Tapping contributes to the gradual destruction of scale and rust. To correctly dismantle the fasteners, you need to take a small hammer and shock shock, trying to turn the methome. This method helps to quickly unscrew the connection.

Effort for twisting should be moderate so that you do not have to drill additional holes. If the process is performed correctly, it is necessary to thoroughly clean the bolts from rust and handle graphite lubricant.

With the help of solvents

How to unscrew, disrupt, cut or unscrew the bolt with torn edges

High-quality compositions against rust and scale are expensive and are the most effective means. However, the market you can find a lot of budget options for domestic production.

The most popular is the aerosol composition of WD 40. The substance quickly penetrates into microcruises and gradually dissolves corrosion. In addition, the kaneylene bolts are unscrewed using brake fluid, kerosene and white spirit. To achieve the maximum effect, you should wet any tissue with a substance and wrap it with a metica for a while.

Thermal method

How to unscrew, disrupt, cut or unscrew the bolt with torn edges

If the above methods do not give the desired result, one output remains - fire. Heating elements and instant cooling allows you to quickly release the threaded connection from scale. After heating with a gas torch or other device, the methis needs to be cooled with machine oil.

In almost any situation, the bolts can be unscrewed by subwoofers. All that will need is flat or cross screwdriver, horn keys, heads, lubricating composition and a little effort.

How to unscrew the screw with a torn head

How to unscrew, disrupt, cut or unscrew the bolt with torn edges

  • How to unscrew the small screw (screw) with a torn head
  • How to screw the screws
  • How to unscrew the torn bolt
  • - small screwdriver;
  • - Super glue;
  • - soldering iron with narrow sting;
  • - Drill and small drill.

As a rule, on the thread of the smallest screws before spinning, paint is applied to increase the strength of the mount. Therefore, if the head is not yet completely torn - try to heat it with a soldering iron with a thin stale. It is important not to overdo it, because If there are plastic parts of the housing next to the screw - they can be sent to the screw.

After heating, immediately try unscrew the screw - it must succumb to it easier. The main thing here is also not to rearrange, so as not to break the threads finally.

If the carving is usually finally, you will help superclones. Drip glue into the torn hole of the head and insert a screwdriver into it. Press the screwdriver to better connect the screw and screwdriver. Do not tent a screwdriver while the glue dries! Waving some time (depending on the speed of drying the glue), neatly, without sharp movements, start unscrew the screw, smoothly adding the force.

Also, instead of glue, you can try to drop the shift, but it is less efficient.

If all of the above measures have not helped, take a drill with a drill, the diameter of which is equal to the diameter of the screw head. Carefully drill only the head (!) Of the screw, trying as little as possible to affect the plastic parts into which the screw is screwed. After you figure out a laptop (phone), a part of the screw will remain stitching from the bottom item of the connection. It can be carefully unscrewed by passage.

For the assembly instead of the drilled screw, it is necessary to use a new screw with a washer (because the diameter of the hole in the plastic has increased after drilling).

We all know that in the modern market product quality everything falls and falls. Someone connects with the desire to reduce costs, someone with a longer service life and therefore replacing the same product or more "modern."

I can not say anything, but lately I often ask how to unscrew the broken screw on the laptop Or other household appliances, after all, twisting and twisting it several times, in a modern laptop, you will most likely break the slots, and it is very unpleasant.

In fact, such a problem is found not only in household appliances and electronics, but in many areas where fasteners are applied and now we will explain, how to unscrew the screw with a torn slot .

How to unscrew the broken screw

To do this, we will take several options.

1. The cooler, but in most cases helps. Just push the screwdriver towards the screw and twist with sufficient effort, so friction will increase and therefore, there is a good chance, slowly but right unscrew the screw with a torn head .

Is a gun a pneumatic gun

How to unscrew, disrupt, cut or unscrew the bolt with torn edgesBy performing repair work, sometimes the question arises: how to unscrew the bolt or screw with torn edges. This task has several solutions, knowing that almost any hardware can be promoted. Even in the case when you stopped and threw the head or broke the hairpin, there are ways and tools that allow you to twist the fasteners.

Preparatory events

Any problem is best prevented than solving. Therefore, if you attached a sufficient effort, and the fastener did not move from the place, you do not need to continue until you damage it completely. Better do the following:

  1. First you need to remove the rust layer and other contaminants. If the threaded part protrudes over the fastened parts, clean it with a metal brush.
  2. Take the hammer and overtake the head. Blows must be quite strong. Nothing terrible if you make small dents on the metal, but it is impossible to allow the curvature of the fastener itself. This procedure helps to disrupt the integrity of oxides, so the positive effect will be only at the initial stage, when the head is pressed to the part. After you have broken a bolt from a place, it is not recommended to knock on it, since the likelihood is that you damage the threads than complicate the position even more.
  3. How to unscrew, disrupt, cut or unscrew the bolt with torn edgesVery good results gives heating the place of attachment. Everything you need is to heat the fastener and wait when it cools. In this case, some of the substances burn out, the rust is destroyed, and the bolt is twisted with a smaller force. Heating should be strong. It can be carried out by a soldering lamp, a gas burner or acetylene cutter. In all cases, an open flame is used, so first make sure that you do not damage the surrounding elements. Do not forget about compliance with safety regulations!
  4. Lubricate a habitat of any easy-to-eat fluid. This can be a special composition of type WD 40, kerosene or brake fluid. Their feature is that they penetrate all the pores and cracks, lubricate the thread, and some destroy rust. For a positive effect, some time must go. Usually recommend waiting for about an hour and start working. In difficult cases, it will be necessary to wait 10-12 hours.
  • The above actions will not be superfluous and in the case when you decide how to unscrew the bolt with torn edges.

Ways to unscrew the bolt

Below are the most effective ways to unscrew the damaged bolts and screws.

With spoiled edges

Determining how to unscrew the bolt with torn edges, you need to consider whether there is access to it, location, and which tool you can use. Based on these factors You can apply one of the ways:

Daewoo Nexia 1998 reviews

  1. The use of chisel. The method is suitable for large bolts to which there are free access. All you need is a hammer and chisel. The chisel is applied on the tangent of the head and apply sharp blows along it. The way is simple, but it infrequently allows you to achieve the desired result. It should only be applied when there is no other tool at hand.
  2. If there is free access to the location of the fastener, you can use a universal stop-key key. This tool allows reliably to hold even a round head. If you use small stopping keys of the "Cobra" type, in which there are sharp notches on the working surfaces, then you can unscrew the smallest bolts. Such a tool can rescue in many cases, but it should be new. In a worn tool, notches can no longer provide reliable grip with metal, and the key will slip.
  3. How to unscrew, disrupt, cut or unscrew the bolt with torn edgesIf the faces are not damaged, they can help the heads for the cape. For these purposes, the profile of a cape key must be with 12 faces (inside the head of the stars, not a hexagon). References are made as follows. Choose the head one size is less than the size of the bolt, and with the help of the hammer, it is turned onto the torn faces, then unscrewed in the usual way.
  4. This method is to use the metal hacksaws, with the help of which the bolt on the head is made under a flat screeching. The depth of the cut should not be more than 75% of the height of the bolt head, with greater depth one of the halves can break.
  5. If your disposal has a file or bulgaria, then you can restore the face of a smaller key. If there is a horn key, cut the hexagon optionally, it is enough to make two parallel faces.
  6. If you can use welding at the location of the attachment, it will greatly facilitate the task. In this case, you can put on the head to put the nut of a suitable diameter and weld them together, and then use the usual keys.

In difficult cases, in order to achieve the desired result, you need to combine several ways. Therefore, first rate the setting, decide how to unscrew the bolt, and only then proceed to work.

With torn head

Very often, sacrificing old threaded connections, you can not only damage the verge of the bolt, but also to rip the head. Then the question arises: how to unscrew the torn bolt. If you disconnect the parts, and the torn bolt protrudes from the body of the part, then you can use all of the above methods.

And how to unscrew the bolt with the torn head, if the body of the bolt does not protrude from the part? There are several options for solving this task.

  1. How to unscrew, disrupt, cut or unscrew the bolt with torn edgesIt is best to apply a special tool - extractor. The extractor is made of a cylindrical metal rod, at one end of which the conical carving of the opposite cutting is located, and on the other - the shank of the square section. In order for it to be used, in the center of the bolt, you need to drill a hole. Hole diameter - 2-3 mm less than the diameter of the thread. After that, you need to take a suitable extractor and slight blow to score it into the hole. Rotating extractor for the shank, unscrew the remains of the bolt.
  2. If there is a tap with left-hand thread, you can successfully apply it as an extractor. The only difference is that the hole diameter should be as to cut the thread. The exact value can be found in the respective tables.
  3. If you unscrew the chip still, you can try to delete it in this way. In the bolt drill a hole of the maximum possible diameter, trying not to damage the threaded connection. Then take the corresponding tap and cut into the thread hole. During this process, the thread is cleared and the residues of the bolt are removed.

Auto mail ru forum

It is quite difficult to drill the hole. And if you damaged the threaded connection, then it is possible to correct the position only by replenishing the hole and cutting the thread of the larger diameter.

The cut pin is not different from the bolt with the torn head, and therefore the methods of its twisting are the same.

Damage to thread

There are cases when the thread of the fastener is damaged. In this case, the methis is freely scrolling, but it does not work out from the threaded connection. To solve this problem, it is necessary to lift the bolt.

It is possible to do this with a screwdriver or another similar tool that is dyed under the head and lifts it with an effort. When the bolt is strengthened, it is starting to rotate in the direction of twisting. This is done until the hardware is completely extracted.

If the hole of the threaded connection is through, then you can push from the reverse side using any tool suitable for this.

How to unscrew, disrupt, cut or unscrew the bolt with torn edges

Under the stall and hexagon

Recently, fasteners with heads under the stall, hexagon and more exotic forms are increasingly used. If the faces on such a fastener are damaged, and you need to unscrew it, you can act by analogy with conventional bolts with the only difference that you need to use a tool with an appropriate face form.

Removing the screw

Many hassle deliver screws with torn faces. Unscrew such screws not easy, but there are several ways to solve this task. In order for them to be easier to turn out, you need to make the same preparatory activities as for bolts.

How to unscrew, disrupt, cut or unscrew the bolt with torn edgesIn the simplest case, when the screw protrudes over the surface, you can try to grasp it with pliers, laying or other similar tool and soak it in such a way. But most often grabbed nothing. Then you can try the following methods:

  1. Sometimes it helps the use of fine rubber, for example, from a balloon. A piece of such rubber is put on top of the screw and unscrew, pressing the scum through it. This allows you to strengthen friction and avoid slipping overlap.
  2. The screw with a figured head can be removed under a flat screeching, peeling the groke.
  3. In order to solve the problem of cleavage slipping, you can apply glue based on cyanoacryl, such adhesive will quickly dry and high quality fastens metal surfaces. The procedure is simple: the screw and diverter are degreased, glue is applied to the screw head and pressed scolding to it, observing the alignment. To accelerate the grasp of glue, you can sprinkle with soda. Wait for the complete hardening of glue and try unscrewing the screw.

In order to further avoid such problems, update all the threaded connections with layers or tags before assembly. Replace the entire fastening with damage. Be sure to lubricate the thread and fastening as a whole. It is best for these purposes to use graphite lubricant.

Very simple advice, how to easily unscrew the screw with torn faces

Those who make in the house repair with their own hands could once encounter such a problem: the screw is tightly pulled to the surface, and the slot (the slot on the fastening product, which inserts the screwdriver) tightly fed.

As a result, unscrewing such a screw is very and very problematic. Usually such a problem happens with edges under the crusader. To unscrew the jar of the passats is difficult and not always possible.

But there is a small lifehak, as easily and without any particular problems unscrew the tightly attached to the surface of the screw with torn faces.

How to unscrew, disrupt, cut or unscrew the bolt with torn edges

To do this, you will need an ordinary gum (or rubber gasket), which will roughly correspond to the screw of the screw.

How to unscrew the "stubborn" bolt?

09/29/2016 How to unscrew, disrupt, cut or unscrew the bolt with torn edges

Before you win "stubborn" fasteners, it is worth carefully understanding - what is the bolted bolted connection in principle?

Bolt is a fastening element in the form of a rod with a thread and hexagon head. It serves to transmit the thread torque of the torque from the tool when unscrewing / twisting the bolt.

In turn, the threaded part (bolt rod) is inserted into the hole of the fastened parts.

And it can either go out - then for mounting and tightening parts to the end of the rod, a nut (with or without washer can also use a spring washer or a package of washers, or lock nut).

Or a bolt can be screwed into a through or deaf opening with internal thread. Then the nut is not required, although under the hex head of the bolt again, the washer can be dressed - to prevent the fastener attempting during operation and / or to protect the surface of the part from damage during the primary fastener tightening.

Of course, in practice there are a variety of bolted bolt connections. However, the tightening of the bolt is always provided through a dense clamp of the protrusions of its thread (outdoor - on the rod) to the protrusions of the feed inner thread nut or hole in the body of the part.

Why doesn't he spin?

From the above, it follows that to twist or unscrewing the bolt, you need to attach a certain force. It is called torque.

This value is very important for the normal functioning of products. And strictly speaking, in the assembly instructions, the recommended moment of the bolt tightening is always indicated (as well as nuts and spills - if available).

Which must be observed using a dynamometer key!

When tightening, the torque is applied to the bolt through its hexagon head.

Consequently, both to twist, and for unscrewing the head must be properly (actually present - after all, there are bolts and with a torn head!), Having smooth, not torn faces, and approach the size to the existing tool (although, of course, this tool is selected. Suitable to the bolt, and not vice versa).

How to unscrew, disrupt, cut or unscrew the bolt with torn edges

According to the logic of things, when unscrewing the bolt, you need to make the same effort as when twisting? And here is not! In the process of work, the bolted joint is prone to self-resolutions (although there is a spontaneous weakening, but this is a separate topic!). Yes, and rust, dirt that fell on the threads leads to the bustling of the connection. So turning the old bolt is much more complicated than wrapping a new one!

It is necessary for an additional torque. However, transfer it to the rod - and successfully unscrew the bolt - it is not always possible. How to promote a bolt with different defects is indicated below.

How to unscrew the bolt with a torn head?

Previous Mount Master put too much efforts when tightening and threw the head? Or the head disappeared at the first attempt to unscrew the old, rusted or "disturbing" bolt? ..

In any case, the part knocking in the body needs to somehow unscrew. The most "painless" way is to apply a special tool "Extractor". In fact, it is a short rod with cone (left!) Threaded at the end and hexagonal attack in the middle.

In the broken rod of the jammed bolt, a shallow hole is drilled, an extractor is inserted, the key clings to its hexagon and rotates to the left. Cone thread Extractor "bits" into the body of the bolt and pulls it to the left - that is, unscrews.

With the help of an extractor, you can not only unscrew the bolt with a broken head, but also with a sharpening thread.

How to unscrew, disrupt, cut or unscrew the bolt with torn edges

Torn edges head

How to unscrew the bolt with torn edges? It is a little easier than the previous case - after all, the bolt remains as much, just for the head it is not possible to reliably hook the key.

In this case, instead of the horn, you can use the challenge key - it will not allow to spoil the head even more. If the verge of the face is strong, so even the head "turns", you need to "drink" a new face with a file - it's not so difficult, as it seems.

Another way: to the head of the bolt with torn edges to privary a new nut. And then unscrew the bolt, clinging the key is already for it. This method is reliable, but labor crews (welding required) and not always appropriate.

How to unscrew, disrupt, cut or unscrew the bolt with torn edges

How to unscrew the bolt with torn thread?

Probably the main reason for the hopping of the bolt is an accurate, rusted or damaged thread.

The first two reasons appear during operation, but you can easily thread the threads and in the process of mounting - twisting the bolt.

Or just when unscrewed, if the contaminated carving creates significant resistance, and an impatient wizard makes too much effort.

If the thread is reduced, and the bolt is located in a hard-to-reach place, its twisting can turn into a whole problem!

To remove a small bolt, you need to try, slightly overlooking it, push under the head of the plug and pull it out, like a nail from the board.

For larger bolts, you will need a screwdriver and a nail: screwdriver need to try to slip under the head of the bolt. And, tapping a hammer on this "lever", at least pull a damaged bolt from the body of the part. Then, you can already shove the nail to the head - and again, like a nail, "torture" the bolt.

However, with such an operation, excessive efforts should be avoided! After all, if the bolt is new, and the carving is reduced when installing is one thing. And if the carving collapsed from time? Then the "cortex" of the bolt may end the broken head. And the question will be the question "How to unscrew the broken bolt?", Which we looked at at the very beginning.

How to unscrew the accurate bolt?

"Jumping" (grabbed by mud and / or patched) thread can be absolutely good (not torn). But due to the presence of dirt or rust in its depressions, the bolt turns out to be "groping in vice."

And excessive force for its unscrewing can just lead to a breakdown of the thread! What is undesirable, since to eliminate the "drainage" and still extract a good bolt much easier than to win the torn thread.

Therefore, before sinning the bolt damage and resort to the power methods of "hardened", it is better to try to fix the harness. To do this, use (required!) The end key or a cape. You can only break the face of the face or take off the bolt head at all! (how to unscrew the broken bolt speak at the beginning of the article)

How to unscrew, disrupt, cut or unscrew the bolt with torn edges

However, before "grinding" the key follows, firstly, thoroughly clean the bolt from the nanile dirt. And secondly, to process its special fluid. The corporate "rust solvent" is best approaching, which includes Molybdenum Distulfate. Also, the penetrating universal lubricant WD-40 is used.

In extreme cases, can be used kerosene, brake fluid or diesel fuel (with great care for security reasons!).

True, deliver a fluid to the thread under the head of the bolt much more difficult than in the case of unscrewing the nut (especially when the thread of the bolt or the studs of the bolt or the hairpins stands for the overalls of the nut), but this step will not hurt.

Waving some time (so far the fluid works), you can start twisting. If the usual end key does not help, it is better to use special precipitant heads with a shock mechanism.

It should be noted that the "dragging" thread occurs not only on aggregates exposed to dirt (for example, in the car suspension). But also on those threads that fasten the nodes working in a significant difference in temperature.

For example, the exhaust manifold of the engine or the selection part of the muffler is very often dismantled with difficulty due to the "accurate" nuts.

Although this fastener is not exposed to strong contamination, its "bipigation" is due to the work under conditions of cyclic heating to high temperatures and multiple cooling.

How to unscrew the bolt with torn edges? Tips of professionals

Any master will agree that the verge of a screw is always broken at the most inopportune moment. It seems novice that it is impossible to get it, but it is not. To feel confident, the builder should know how to unscrew the bolt with torn faces.

Why does it happen?

This situation may occur due to the fact that the screw or tool that is used has already been worn out. When the contact of screwdriver with a screw is not sufficiently dense, the ribs begin to "merge".

If the master applies a small force to the tool while working, it can provoke the destruction of the faces.

What needs to be taken?

In order not to exacerbate the problem, you need to stop all actions immediately after the sting of the screwdriver began to scroll or scroll. It should not be persistently continue to move, as it will not lead to anything good. Now the main thing is to get a bolt without damaging the material in which it is located.

Change screwdriver

The next step is the replacement of an old screwdriver to a new one, which sting not worn. With this tool, you can try to unscrew the screw. Before the start of work, make sure that the sting of the screwdriver tightly entered the grooves.

If the screwdriver still slides, it is necessary to find other ways to unscrew the bolt with torn edges.

If the screw is not twisted ...

In the case when the bolt is not fully entered into the material, you can try to pull it out with the passats. To do this, you must grasp the head from the sides. It is necessary to rotate slowly and in the opposite side from the course of the clockwise. As a rule, after several neat manipulations, the screw is removed from the surface.

It can be used to the metal with metal when the screw is not completely twisted. It is necessary to perform a small propyl, approximately 1-2 mm, and then the screwdriver try to tweak the stuck screw. The sting must necessarily be acute, otherwise you can still "lick" the face of the cap.

Using flames

If the material is fire-resistant and tolerate high temperature values, you can try to remove it with a match or lighter. When heated, the screw is slightly increased in size, respectively, the material will be burned.

When he cools and will have initial dimensions, a tiny clearance should arise between it and the main surface. Then, using pliers, extract the screw will not be much labor.

WD-40

This lubricating liquid is simply indispensable in situations when you need to unscrew the bolt with torn edges. It must be sprayed into the microscopic gap, which is available between the screw and the material. The lubricant will reduce the strength of friction and it will be easier to get it.

When no method helps, it remains to drill a screw. This can be done both completely and half, and then screw the extractor and remove the bolt.

Auxiliary methods

Experienced masters recommend to cut the head of the screw with a grinder or cut down to chisel. Next, you should select a smaller drill and drill a bolt. If necessary, the action should be repeated, slightly increasing the size of the drill.

If the screw is small, you should beat it towards unscrewing. You can also use drills with left rotation. The speed should be small.

Stilkovit

Masters who often face a problem how to unscrew the bolt with torn faces, it is worth thinking about the purchase of a special tool. Studberman helps unscrew the screw with a fully torn head. But from its use will be a positive result only when it was possible to make several revolutions.

Causes of breaking faces

Not always the desire to quickly replace the failed parts fixed with the threaded connection is performed. Sometimes, trying to unscrew the bolt from the body of the unit, the key begins to scroll.

So that breaks down the faces on the head of the metric when exposed to an increased load. And the following factors may be the result:

  • harness that is caused by the diffusion of atoms with a debt of the connection;
  • Displacement of parts connected relative to the axis of the holes, which leads to the screwing of the screw;
  • Tightening during installation (increased load);
  • Using an inappropriate tool during assembly (for example, to spin the bolt, the cap size of which is 14 mm, the key is used to 17, and a screwdriver is inserted to remove the gap);
  • Corrosion seized the surface of the head.

How to unscrew the head bolt under the hexagon or asterisk

In the automotive industry, other equipment often use bolts under the hexagonal tool. How to unscrew the tornbeach, which is breaking the face:

  • Make a horizontal bowl with a grinder or a file on a hat. To unscrew the torn screw, at this case, a strong screwdriver is used.
  • Using a special TORX sprocket, which is driven into a hat. The nozzle is selected in size, slightly torn the hats, for a durable connection between the walls.
  • A set of extractors that may be purchased in a shopping store. Before using the extractor, the hole drill is drilled at the base of the bolt, then the extractor is introduced, the screw is extracted with a pliers or a special clamp.
  • The use of drill with left rotation, slightly smaller on the diameter of the hole. The tool is performed in reverse mode, with this method it is possible to ruin the thread.

How to unscrew the bolt with torn edges manually

Torn nuts are getting out more difficult, since when working there is a chance of damage to the thread. The easiest way is the use of chemicals, surface processing is cleaned and processed by a means for 15 minutes. When torn edges, apply the key or head is impossible. In such cases, the chisel is used, which is destroyed by the bulk of the nut, is then removed and replaced with a new nut.

How to remove the bolt if the head broke

The broken head of the design can deliver a lot of trouble when working. How to act with such a difficult situation without resorting to the use of a serious tool. With small sizes of the element, it is possible to do with a grinder, the deepening of which will allow you to use a screwdriver with sharp edges. To perform more complex works, you need an extractor, drill and sweep. The base of the threaded connection is dried exactly in the middle, after the manufacture of the hole, the instrument is screwed down the clockwise.

When performing consecutive actions, unscrew the damaged element of the structure will not be difficult for those who are first faced with this problem. It is necessary to competently assess the situation, use a good quality tool for productive results.

How to drill a broken bolt

For work used drill from high-quality material. The size must be selected in accordance with the torn edges, the diameter of the drill should not be greater than the hole. High-quality drill is characterized by an increased price, but its use eliminates rapid wear and the possibility of breakage in the work process.

Use the tool is not rush, before performing the task, competently assess the situation. It is necessary to monitor the position of the instrument in the process of operation, drill is made strictly in the center, without deviations in different directions.

Opplish flush

This type of breakage is considered the most difficult to repair, as it is very difficult to determine the diameter of the opening, especially when cutting fasteners. Therefore, in order to extended a broken bolt of a certain species, it is necessary to clean the surface. This will determine the clearances we need.

It is often happening the following unpleasant situation: the breakdown of the cliff has curves that are very difficult to process and straighten. And to drill the product in a similar state is categorically not recommended, for there is a risk of finally handle the design. Therefore, you first need to apply the core, which is prepared the place in the center of the operation of the drill.

Further order of action, allowing to drill a bolt bevelled in one way or another, similar to the surface cliff. After creating the hole, the residues from the thread is removed using the hook.

Methods of unscrewing bolts, screws, screws with linked edges

If the usual way it did not work out to unscrew the fasteners, which shoved the edges, you can use one of several proven options.

Gas key

This method is used when unscrewed bolts, since they are headed by a head for which you can grasp. For this:

  1. Clean the head of the bolt.
  2. Lubricate the connection of the kerosene or diesel fuel, the liquid of type WD-40 helps well, and leave for 15-20 minutes.
  3. Remove the bolt. Do this gas key. With it, it creates a lot of effort and it is possible to capture even a round head.

The lack of such a method is that it is not always possible to get a gas key to the right bolt.

Cutting new faces

If a big bolt, then with the help of a grinder on it, you can cut new facets. It is enough to make them only 4 and with the help of a smaller key to unscrew the bolt. You can cut new facets on the bolt with a file, but it is more complicated longer. On the screw of the screw or screw, you can make a break with the help of a handwheel on metal or a grinder.

On the screw of the screw or screw can be made a deeper incision for turning

Hammer and chisel or shock

This option is more suitable for linked nuts or sufficiently large screws. The chisel rests into the head of the fastener element and, hitting the hammer on it, gradually turn the screw or nut. Small screws or screws can be unscrewed by shocking and hammer. After weakening fastening, the work is performed by the usual scolder.

Impact scaffolding can be unscrewed small screws or screws with linked slots

Harness or piece of rubber

In this case, a small part of a medical harness or a piece of dense rubber is used. The selected material is placed on top on the head of the screw or screw, after which they pressed the scolding and gradually turn it. The presence of rubber will help increase friction and solve the problem.

Harness laid between scolding and screwing screw or screw

Extractor

The extractor is a special tool that is used to unscrew the screws, bolts or screws with linked or broken heads.

Extractor - tool for unscrewing screws, bolts or screws with linked or broken heads

The order of its application:

  1. With the help of a thin drill in the head make a small hole. In some cases, the extractor can simply score the screw slot into the muted slot.
  2. Select the extractor of the required diameter. Drive or screw it into the prepared hole. It depends on whether the usual or screw tool is applied.
  3. Unscrew the bolt.

Video: Out of the muted screw with the extractor

Normal or left-hand drill

On sale there is left-sided swelling with a rotation counterclockwise. They improve the centering of the tool and reduce the load on the drill, which gives higher performance and accuracy of drilling. By inserting such a tool into a drill, you can unscrew the screw or screw with the jammed head. If there is no left-sided drill, you can try driving stuck fasteners using usual. In this case, you need to take the drill, the diameter of which is less than the diameter of the bolt or screw

It is necessary to act carefully so that you do not have to cut the thread for a new fastener

The drill must have a diameter less than a problem bolt

Glue

To the head of the problem screw or screw with epoxy glue or glue called "Cold welding" fix the nut of the corresponding diameter. After the glue reliably attaches it, with the help of the key turns the nut and turn off the screw or shock with it.

With the help of glue to the linked head fix the nut, and then the screw is unscrewed with it

Welding

If there is a welding machine nearby, then a new nut on the head of the bolt or screw can be welded. After that it can be immediately unscrewed.

You can spend a new nut to a problem bolt or screw

Solder and soldering iron

If you need to unscrew a small screw or a screw, a soldering iron and solder are used:

  1. Preheated solder dripped on the head of the fastening element with linked edges.
  2. While the tin is not frozen, the scum in it is inserted and expect a few minutes.

  3. Remove the problem screw and clean the sting of a shower from the solder.

Drilling

One of the methods that allows you to remove rust and boiled bolts, destroying them completely. It is used in cases when the bolt is scrolled. This method is especially convenient if the edges of the head (mucus) were disturbed during the operation of the mechanism.

After selecting the drill, it is necessary to achieve the elimination of the effect of drill the drill in the process of drilling. To solve this problem, apply adaptations called conductor. Structurally is a plate with holes in which the sleeves are inserted equal to the diameter of the drill. They do not allow to leave the drill towards the work.

If a large diameter fastener is drilled by two holes on the side of the center to a depth of ten millimeters. Paste metal pins (nails, studs of a suitable diameter) and try to turn the old bolt.

If the thread succumbed - the task is solved. If not, you should fly the hole completely to the entire depth or throughout. Then remove the remnants of the metal.

Bolt breakage below the surface

Complex fault, especially for soft metal parts

Therefore it is very important to unscrew the broken bolt without damaging the threads in the hole. The procedure here is the following:

  • It is planned by the center of metizm with core. It is best to apply a thin and durable metal tool, it does not hurt the product;
  • Then the tap having a reverse thread is purchased. The diameter of it must be less compared to the diameter of the bolt;
  • Not a very deep hole under the tap;
  • A tool is installed to cut the thread. It turns around in a circle and then the element can be unscrewed.

https://youtube.com/watch?v=dc8kjmfpx-s.

If the last item failed to implement, the tool can become directly bolt. However, it is not worth the excessive effort, since there is a chance to break it. As a result, you can remove the old broken part and spin new items.

With the help of a drill

You can try to drill the bolt residues with a drill close to the size of the bolt. After drilling, remove the residues of the bolt with a screwdriver.

It should be remembered that a certain skill is required to carry out such a type of drilling, so that it would not damage the thread of the hole.

If the instructions described how to unscrew the broken bolt, you did not help you, then you can use another way.

If the part design allows you to drill the scene of a broken bolt with a large drill, then cut the new thread of the large diameter and tighten the appropriate bolt.

If you do not have the opportunity to twist a big bolt, then you will have to search in the store or find a locksmith, or tokar, which will make you a sleeve with a large external diameter for a new hole. Decreases a smaller inner thread on the sleeve, which will be suitable for your design.

On the Internet you can find various photos of broken bolts and tips of various professionals, which describe the entire work process on the unscrewing of a broken bolt.

This article describes the simplest options that you can use to remove the broken bolt. But sometimes bolts or studs break in the most inappropriate places.

To eliminate this problem, you will most likely have to appeal to certain specialists who, due to their professional activities, there are a lot of ideas how to unscrew the broken bolt from any hard to reach place.

How to prevent breaking faces

In order for such a problem, like torn faces of the bolt or the slot of the screw, the screw did not find you surprise, you need to stick to simple rules:

  • You only need to buy high-quality fasteners that have high strength and reliability;
  • During twisting and unscrewing screws or screws, it is impossible to slip screwdrivers in the slots. This leads to their erasure and unscrew this fastener will be difficult;
  • Always need to follow the state of the instrument. If you have a screwdriver or key jamming, then with their help it will be difficult to unscrew the screw, bolt or screw.

It is much easier to prevent the licking of the faces on bolts, screws and screws than to unscrew damaged fasteners.

Do not panic when such a problem appears as the muted head of the bolt or slot on the screw head, screw. There are many ways to solve it. It is necessary to adequately evaluate the situation that has arisen, and select one of the available options.

How to unscrew the broken bolt

With an insufficient seizure area for a pipe key, attempts to use the tool in this situation are practically useless. It is necessary to use a file, for the manufacture of faces on a torn product of a smaller diameter. After successful processing, the key or the head is selected, you need a diameter, smoothly unscrewed the resulting element.

Revealing of the torn bolt

Using the hammer together with the chisel can make it easier for labor, it is necessary to make a notch and accurate blows to reveal the tool. This method is considered effective, as the shock force acts on the right side. As soon as it is visually determined that the process has moved from the place, you can use a suitable cape key or head.

If there is a welding machine under hand, you need to screw the nut on the hat, then with a sharp movement it is possible to unscrew the torn part. In cases where the nuts nut is not possible because of the lack of space, a piece of metal is boiled for further faces.

As the element of the connection with the torn edges will be twisted, experienced masters will tell, some simply begin to drill without losing time. An effective way is to eliminate the washer between the bolt and the clamping area. The hammer is applied to the chisel installed on the nut.

Methods that you can unscrew the bolts

Extractors of broken bolts

There are several ways to unscrew the broken bolt. Consider them in more detail.

With the top of the bolt with the head

When deformed on it, peculiar "mustaches, which can be cluttered for the remaining part of the bolt in the hole

The easiest way to unscrew the broken, but well-lubricated when twisting the bolt is to take advantage of it already broken upper.

The probability of success when using this method is small, but it is worth trying, in particular, if the bolt breakdown occurred at the initial stage of cheese.

Using a small screwdriver or chisel

Twisting damaged bolts

You can try to unscrew the residues of the bolt, if you use a screwdriver or a chisel of small sizes. At the same time there are two versions of actions: either just unscrew the broken part, using irregularities on the site of the break, or make a similar slot on the upper side of the broken part, clinging to the edges of which and produce twisting.

The last method is implemented only if the material from which the chisel is made or turning has a higher strength than the material from which the bolt was made.

Using an extractor

Extractor is a drill having a long cone-shaped tip

This is the most effective way, since it is possible to achieve a result with it. Features of the device of extractors are that they are screwed into the hole located in the central part of the bolt of the bolt. In this case, the thread present on the extractor has the opposite direction of the bolt thread (the so-called "Left thread").

Usually, in the sold sets there are several drills of different diameters

All of them have the same shape, while on the other hand there is a rectangular mount for a drill or a tap relative to cone-shaped thread.

In the process of screwing into a bolt, the extractor cries it and will stop at some point. Further rotational motion is transmitted through the extractor to the bolt and unscrews it.

Consider the sequence of actions that must be done to unscrew the torn bolt with the extractor.

№1 Bolt residues

It is recommended to make a sleeve of a small length, from the outer part of which to cut the thread with a pitch equal to the thread of the hole in which the torn bolt was twisted

1

Initially, it is necessary to make a hole in the residues of a broken bolt. This is a very difficult operation, since the diameter of the bolt is relatively small. In addition, when drilling, you need to be very careful not to damage the thread.

At the same time, two drills are used with a different form of the tip - with a stupid and sharp angle

2

In the center of the bushings you need to do a hole sufficient to pass the drill, which will be reserved the bolt residues.

Unfortunately, this method is not always applicable, because it is necessary to have a lathe for its implementation. Therefore, another method is applied.

The first is used to align the top of the bolt residues, and the second is directly for the drilling of the opening for the extractor. In this case, the diameter of the drill with a tip having a stupid angle should be a little less than the diameter of the threaded hole. The diameter of the second drill must be equal to the diameter of the extractor.

№2 Spinning extractor

Pliers use undesirable because they lead to the "licking" of the rectangular end of the extractor

1

Further, everything is simple - the appropriate diameter extractor is twisted into the resulting hole

It should also be done carefully, if possible at low speed. You need to use the correct tool to twist the extractor (tap or special nozzle on a square cross section) so as not to spoil its mount from the opposite side

As a last resort, you can to the end of the extractor to weld the appropriate nut to the bolt to do with a normal key

Next, the extractor is twisted into the bolt and rotates in it until it stops.

Further rotation of the extractor leads to the unscrewing of the bolt residues

In order not to deal with such problems, it is best to warn them. Do it easy and special problems will not deliver such work.

Before "tightly" tighten the bolt, the hole must be abundantly lubricated "WD-40" or diesel. After some time you need to screw themselves several times and unscrew the bolt. It remains to lubricate his thread, after which you can stretch it.

Another good facility is a candle paraffin. They need to grasp the threads of the bolt before screwing it. It will be not bad after a complete broach a little warm up a methy between the usual gas burner. Paraffin will melt and fill all the smallest emptiness. After these actions, corrosion simply will not be chances.

It makes sense to keep a couple of candles in the garage - it is unknown, for which they can come in hand in handy: anugrahjayabandung.blogspot.com

Is it worth using soap for lubricating thread

The answer to this question is unambiguous - in no case. The fact is that in the manufacture of both the economic and toilet soap, it is used picked. Its amount is negligible, however, this is enough to initiate the metal oxidation process. As a result, sinks appear on the bolt, as well as on the part. They are connected in the corrosion process, and after some six months, it will not be possible to unscrew the methomems even with the help of an extractor. Such a process in commoner is called the harness.

Self-torn Slots (asterisk)

If the shifted screws were twisted a couple of times / twisted, their verges lose their sharpness, the screwdriver scrolls, and the screw itself remains on the spot. If he "sits" in wood, plaster, chipboard or other similar, not too hard materials, you can put a thin rubber for a screwdriver (for example, for hair). Due to the strength of the elasticity, it is achieved a more dense fit to the remaining faces, which helps to shift the self-sighs. The remaining methods are more "traumatic":

  • Cut the grooves inside the "jammed" funnel using a flat screwdriver, unscrew. This method is sufficiently dangerous: if the walls of the "funnels" are too thin, there is a possibility that the screw head will simply turn away from the effort. There will be only a screw that will not get unscrewed.

  • Drive and unscrew using a small diameter extractor.
  • Take the chisel to sharpen it in size with the hat. Put it on the hat, a couple of times spacing a hammer. A new hat is formed and, at the same time, there may be a crush the existing rust (if the screws are stuck in the gland). With the help of the same chisel to try to shift the stubborn screw from the scene. To facilitate the process, you can drop the oil on the wood or lubricant WD40 for metal.
  • Drive around the hat material, take a tube with an inner diameter of a little more diameter of the hat, put it on a hat. Pour glue inside. When glue freezes, unscrew the tube.

The remains of the bolt or hairpins without a hat can be unscrewed like this: cut the left thread in the remaining body, drop by glue "moment", screw the left tap, leave for an hour. On the main thread drip oil and also leave for an hour. When glue grabbing, unscrew. If the wood stuck the remnants of screw screws in the wood, it is easier to close this hole and set to install another fastener.

How to unscrew the bolt with torn edges?

Very well, if there is a space that allows you to use such instruments to be used to spinning to spinning or passataging.

Bolt with torn edges under a screwdriver

If access to the bolt with torn edges is limited, then you can make a bolt on a bolt hack or with a grinder. After that, you need to try to unscrew it with a screwdriver, and if it does not succumb to it again, then put a screwdriver at an angle to the busty bolt and beat it with a hammer, trying to create a rotational movement (counterclockwise).

Bolt having a protruding head for an inner hexagon or an asterisk

Such a bolt can be twisted:

A flat screwdriver, after hacking on a cop of the bolt with a bolt with a knife for metal or a grinder (it is important to perform a cut with absolutely vertical walls so that the screwdriver does not swash the screwdriver); using the TORX sprocket with a suitable size (selected so that it does not pass into the hole under Hexagon, but not too big). Such an asterisk should cut a bolt haat with a slot, entering tightly in the hat itself

Then you should unscrew the bolt of the jerk to avoid a breakdown of the sprocket. You do not need to use for this manipulation of TORX sprockets having holes in the center, because when driving, they are laid out. Drills help drills, drills and a set of special extractors (sold in construction and automata). For this, strictly in the center of the bolt drill a hole, carefully score an extractor of a suitable size in it, and then unscrew it with the pliers with a bolt. It will simply do, since the extractor has the direction of cutting the threads opposite to the bolt. Drill a drill with a reverse and left rotation drill, the diameter of which should be slightly smaller than the damaged bolt. Initially, a small thin drill is made a small hole, and then in a drill put the left rotation drill and turn on the drill to the invertive rotation mode.

Bolt having a hole under the hexagon

Such a bolt can be twisted:

  • Using the feet for the next size under the hexagon (in this case, the bolt can even be used again);
  • Using the TORX asterisk of a suitable size;
  • Flat screwdriver, hacking on a metal or a grinder on a bolt hacking on the hat;
  • With the extractor, which is screwed right into the hole under the hexagon.

Bolts of steel rods

Such a bolt can be twisted:

  • With the help of an extractor of a suitable size;
  • With the help of electric welding. To do this, insert and welcome an unnecessary hexagon that corresponds to the size of the bolt. It should be noted that this method is suitable only for bolts made of steel.

Alternative methods

One of these methods is the welding of the nut on the broken part of the rod. It is effective enough if part of the bolt is located above the surface of the part. To implement this method, you need a hammer, a welding machine, a grinding tool (manual or mechanical), the nut of the desired size.

At the initial stage, preparatory work is produced. They consist in processing the remainder: stripping, removing corrosion traces and degreasing. Using the tool, fix the nut in the center of the rod. The welding machine is welded to the top. The assembled design is neatly unscrewed from the hole.

This method is used if the reason for the bolt is not toothed corrosion or the so-called welding of the bolt with the part of the part. To implement this method, various solutions are used. They consist of acid (for example, sulfur) and various additives. Recently, the special composition of WD-40 has become wide popularity. In many cases, he becomes a good assistant to solve the task of unscrewing "difficult" or broken bolts. This composition is advisable to apply with all the considered methods, except for thermal, since it is quite a fuel.

Serve the chip

The most time consuming is the drilling of broken bolts. It is worth using it only in extreme cases when other methods are not suitable. This is due to several reasons. First, it is necessary to high accuracy of the work carried out, since the probability of damage to the thread is very large. Secondly, break the bolt will not be so easy, it will take time and several sizes of drills.

If there is no skill of such work, the most acceptable option will use a thin drill to start, and then a larger diameter. The meaning of the method is the choice of size, which will be as close as possible to the size of the hairpins. After the work carried out, the bolt chip must be removed using a magnet.

Bolt-star

You can unscrew a similar bolt as well as unscrew the nut with torn faces. The main ways of unscrewing the unsuitable bolts and nuts were disassembled very detailed by us earlier, and now we can summarize all the ways that are suitable for such a screw. So, if your bolt-starf has a breakdown:

  • The easiest way to use the extractor. Excellent proven tool will not let and this time. Perform a hole in the foot of the fastener, lock there the suitable extractor and cautious movements to unscrew the stuck bolt. As we see from this article, a set of extractors of various diameters - a thing really necessary in the farm, if you regularly do similar assemblies and disassembly.
  • Use the gas key. This adjustable key tightly takes a bolt, and you can extract it into several turns. This method is good because you do not need to buy a separate tool. There is a similar adjustment key in almost every home.
  • Focus on a bolt hat. In the presence of sufficient space around the bolk. Do you wrote onto his hat with a grinder or hacksaw. In this notch, you will be able to double the screwdriver or the chisel and turn the bolt, hitting the hammer or other tool comfortable at its free end.

We looked at the options for the release of bolts and nuts that are available for use to any home master. Of course, the methods used on professional workshops or in car services remained beyond the discussion. However, the equipment is constantly used, which at home you will be useful once or twice. And it is worth a lot of money. Professionals are used to release bolts with torn edges:

  1. Wheel.
  2. Spilingter.
  3. Specialized extractors.

However, if such situations arise with you no more than once a year, then there is no particular sense to acquire special tools.

Rusted nut

Another problem that is familiar to motorists (and not only) is a rusted nut and / or carving. In this case, you should not make the heroic effort to unscrew the fasteners. You simply "lie" the edges and to the boiled thread will add another problem. If after a pair of attempts, it is impossible to unscrew, alternately try the following methods:

  • Spanner tapping a bolt. There is a possibility that the rust will crack and the nut will be able to unscrew.
  • Pour the connection of kerosene and wait. He is a rust jack, after which the rusted nut will be unscrewed easier. But with this operation, it is impossible to smoke, turn on the welding, be located near the open fire.

  • Heat the nut. Metal will expand that it will give it to unscrew it. The entire focus is that the nut begged, and the rod of the bolt remained cold, so the heating should be quick. To do this, use a construction hairdryer or open fire (more careful). If the screw is small, you can take a powerful soldering iron, warm it up to the maximum temperature, then quickly warm the connection site.
  • This method will destroy (almost) nut, so it should be applied only in hopeless situations. Roots are made on the edges (with a saw for metal, grinder, a file). This groove rests on a flat screwdriver, giving it a direction towards unscrewing. The handle knocks the hammer. If there is at least a pair of skills, maybe it will turn out.

  • Use a special puller (in the photo above). With the help of a bolt, pin rests into one of the faces, after which you can try to move it from the spot. Due to the fact that you can put a lever, it can even work in very difficult situations.

Still with rust you can fight with lubrication. Try pouring the place of the fluid universal lubricant (there is in WD40 springs). Waving a couple of hours, we try to work the key. I did not work - we try other ways alternately.
