Everyone who did, came across this problem: the screw is attracted close to the surface, and the slot (the slot on the head of the fastener in which the end of the screwdriver is inserted) is rugged tightly. Accordingly, to unscrew this screw problematic. Most often it happens with edges under cross screwdriver.

You can try to unscrew the jar of passage, but it does not always help. If you crush the cap, then the screw must remain inside the body of the material forever.

But do not despair, unscrew sculp with torn faces possibly. Few people know about it ingenious trickbut he really works! Even a woman can easily cope. Be sure to take this idea for weapons, because the verge of a screw can be broken at the most inopportune moment.

How to unscrew the screw

This is a real creative laboratory! The team of true like-minded people, each of which is a specialist in his business, united by a common goal: to help people. We create materials that are really worth sharing, and the source of inexhamable inspiration serve for us favorite readers!

The use of screws for attaching any products is convenient and reliable. But it often happens that it is necessary to urgently unscrew the screw, and there is no suitable screwdriver under hand. Of course, the use of a screwdriver is the easiest and safest method, but if necessary, it is possible to do without it. How to unscrew the screw without screwdriver? Today you will learn about it!

Let's start off with, screw - this is a cylindrical rod with a special head to be applied by a screw groove. Screws are made for a whole row regulatory documents, among which GOST 1144-80, GOST 1145-80, etc.

At the same time, there are two main types of hardware - this is:

• classic screws;
• self-tapping (also known as self-tapping screws).

To designate, in this case, the diameter and the length of the screw (for example, the product with a diameter of 5 mm and a length of 3.5 cm will be designated as 5x35 mm). In addition, hardware can be classified in the shape of a slot and features of the head itself:

• with a flat (secret) head;
• with the same, but reduced type;
• with pressshaba;
• with hemispherical head.

All these types are made with a cross-shaped slot, with direct (flat) and with TORX Slot (the latter is still known as the "asterisk"), as well as with the inner hexagon and other, less popular options. There are still self-tapping screws with a head of six and eight-marched shape (roofing), which are also made with different slots.

On a note! By type of thread, the screws are also divided into several types, which is determined primarily connected by materials and concrete meal (for metal, on wood, for drywall or small household appliances).

Ways to unscrew the screw without screwdriver

Consider the very effective methods Depending on the specific type of slot. Let's start with the cruciform.

NO1 option. Conducting Schlit

To begin with, we note that some screws have one deepening on the head can be longer than the other. If so, then it should only work with a deepening of greater length to simplify the task. We also add that the faces of these recesses can be arranged, and therefore it is necessary to work carefully, otherwise you can spoil the product.

One of the most simple ways - This is the use of coins. The method works often only with small screws. The coin must be inserted into the groove, and then turn counterclockwise.

Weakly twisted screw can try to unscrew the nail. Actions are the same as in the previous method.

Take the knife, place in the recess (long, if they different lengths) And scroll down. Be careful, because if the screw is very twisted, and the knife you use is low quality, then it is (knife), without achieving the desired result.

Step 5. Use the old CD. Place it the edge into the groove and check. The CD itself as a result of such manipulations may suffer, and therefore make sure that it is no longer needed. The method will not definitely help with a highly twisted screw.

Step 6. You can cut a long groove on the head with a handwheel on the metal, but this method is effective only with a not fully twisted hardware, i.e., if the head is somewhat over the surface. Keep the saw at right angles relative to the head, saw slowly and carefully. Further, when the groove is ready, the screw is mounted with a flat screwdriver or recessive means (for example, credit card).

Step 7. Take a flat screwdriver of a suitable size in the absence of cruciform. What is characteristic, it can work only with large / medium-sized diameter screws. Carefully, not to break the face of the slot!

Step 8. Another option is to use a toothbrush. To install her end to the lighter, after which you immediately insert it into the recess on the screw of the screw. After waiting for the melted plastic froze, check the brush counterclockwise. Of course, it will not help if the screw is twisted too much.

Option NO2. Flat Schlit

As noted earlier, only one deepening on the head of such a screw. In the absence of a flat screwdriver, the product can be unscrewed by appropriate means. Let's see how it can be done.

Use a credit card - insert it into the groove and try to check. Use only an unnecessary card, because it may be completely damaged during twisting.

You can also take "UCHO" from tin cans (from under soda, beer). Insert the broken "ear" into the groove on the head of the hardware, scroll.

Use the usual coin - insert it into the groove and still try to turn.

Step 5. If the screw is not very twisted, you can try to unscrew it with a nail. The method is not always effective in view of obvious reasons.

Step 6. Try to unscrew the screw with a knife by inserting the last bridge in the groove. At the same time there will be a risk that you light knife.

Step 7. Last method - Use of pliers. Suitable if the screw is not completely twisted. It is advisable to use sturgeon pliers for this, and not ordinary.

NO3 option. Unscrew the screw with the TORX slot

Speech here comes on screws with a notch in the form of a six-legged star on the head. Such screws, by the way, are protected - with a rod in the center of the star. In any case, act carefully, because the faces of such a slot can easily be damaged.

Try to cope with a flat screwdriver. Insert her sting on the opposite rays into a couple of opposite rays, rightfully scrolling counterclockwise. And if the screw is protected, then insert a screwdriver between the rod and any of the rays, and scroll into the opposite direction.

To unsalted the protected TORX screw, try apply a screwdriver for unprotected, but in this case the core on the head will have to be removed (this can be done, for example, with kerner and hammer).

Another possible variant - Drill on the tip of a regular screwdriver hole under the rod stars.

Finally, you can use the same toothbrush, melting one end with a lighter (act just as described in one of the previous ways).

NO4 option. Unscrew the little screw

Immediately alleged that small screws are especially difficult to unscrew, without having appropriate tools at hand. As a rule, such screws are found in various electronic devices. Ideally, the tools intended for the repair of glasses should be used (with their finding no difficulties, and they are not very expensive). If there are no such equipment, resort to one of the methods described below.

Table NO1. How to unscrew the little screw.

Steps, photos	Description of action
	Use the knife - Place your sharp end in the slot and try scrolling. It is advisable to insert the tip under a minor angle to increase the area of \u200b\u200bcontact.
	Use a nail file. Act with analogy with the previous way.
	If there are small pointed scissors at hand, you can use them. But we immediately note that such scissors are not the best way To unscrew the screws.
	Use tweezers. Insert his sharp end into the groove and try to turn.

On a note! Another good option is the use of a conventional nail, the tetrahedral edge of which is ideal for a cross-shaped slot. For example, for screws mobile phone A 80 mm nail is suitable.

Sculp with torn faces

Flat / hemispherical head screws (or rather, slots) are often broken, and there may be several reasons for any reason:

• the use of an old, low-quality or unsuitable tool;
• incorrect screwing (hammer, for example);
• insufficient effort when unscrewing / twisting and, as a result, popping screwdriver from the slot;
• "Zakusaniya" screws (corrosion);
• the incorrect use of methization (without deploying, COGDO is necessary, or for an inappropriate material).

Method NO1. Split

Carefully inspect the screwdriver, which twisted the screw, and, if necessary, change to a more appropriate. It is important that the sting is tightly entered into the groove and was not damaged. If the replacement of the screwdriver did not help, you can use other ways. If necessary, for example, an unscrew the screw from the wooden product, then hit the head, and then tapping on the tool each time the effort is applied. You can also use pliers, if possible, what we have already mentioned above. Or you can use to seal the gum.

On a note! In order for the self-tapping screw to scroll, use a few drops of lubricating or brake fluid, kerosene. It is also necessary to heat the screw so that it expands - so the material surrounding it is deformed, and the product can be turned out.

If nothing helps, you can take radical measures.

Method NO2. Singing

Screwing of any type can be tried to unscrew with a flat screwdriver. Using the grinder or handwheel on metal, run in the screw head of the straight slot. But remember that the slot should be a depth of at least ½ head height, otherwise you risk destroying it. This method Can be used in a complex with others.

Method NO3. Extractors

Another good way to unscrew the screw. Pick up the drill so that its diameter is less than that at the threaded part of the methome, do the depression in the head, cut the left thread there and unscrew the screw with the help of conical extractors. This is suitable for all types of heads, however, in the case of self-drawing, you will have to choose another method - they are produced hardened.

What conclusions can be done? If you need to unscrew the screw with torn edges, then it is easiest to do this by welding (or gluing if the force is too large) nuts or some stop to the remaining part of the methome, heating and performing propyl.

Video - how to unscrew the linked screw

Fixing screws of any products, convenient and reliable way. However, almost everyone who at least once twisted or unscrewed the screw with a semicircular head or a secret head out of the wall, the board, came across a problem, how to unscrew the screw if he was torn to a crusader under a screwdriver. Let's try to figure out how unscrewing do more efficient.

Types and types of screws

Screws are cylindrical rods with an applied screw groove and an formed head. Hardware is made according to GOST 1144-80, GOST 1145-80, GOST 10619-80, 10620-80, 10621-80, DIN, ISO.

Two main types of screws: self-tapping ("self-tapping") and, in fact, "classic" screw. When the metric designation is most often used its diameter, length (for example, 5x35 mm, the Self-cutting length is 35 mm, a diameter of 5 mm).

They are classified by the design of the head and the execution of the slot under the screwdriver:

• With a secret head (screw with a flat head);
• With reduced secret;
• With hemispherical;
• With pressshaba.

All the above types can be made with a direct slot, with cruciform, with the TORX slot (in use - "asterisk"), an internal hexagon and a number of others less common. Also possible combinations of slots (for example, direct and crucible).

Separately, you can select screws screws with six, octalized head "turnkey" (roofing screws), they can also be made with different slots.

There are also screws with special heads (screw ring, screw hook, screwpipe, furniture screws (confirmates, although in logic it is more correct to name - furniture screws), etc.

According to the type of threaded part, it is also divided into types of types, due to primarily use and fastened materials (self-tapping screw, screws for drywall, screws for shallow household appliances), In this article we will not dwell on this classification.

All hardware can be made as coated (chemical phosphatated, galvanized), so without it.
Why the screw with a flat head is broken or with a hemispherical head.

More precisely, the slot is broken in his head. The reasons for the face of faces can be quite a lot, we will analyze the main of them:

1. The use of poor quality, inappropriate in size (type) or a worn tool;
2. The application is insufficient (and as a result, the population of the tool from the slot) or excessive effort during wrapping or turning;
3. The use of self-pressing self-appointment (an attempt to screw in inappropriate material, without preliminary zero, when it is required, etc.);
4. Corrosion in the product, both head screws and screw screws (so-called "zakisania")
5. Incorrect overtaking ("hammering").

Minding

So, how to unscrew the screw universal with a secret head or self-tapping screw with torn faces or worse than hats without a hat at all.

The first thing you need to do is inspect the tool with which it is turned out and replaced it to suitable. The sting of the tool should be tightly into the slot and not worn.

To reconcile the screw, the screwdriver must fully fit the shape and size of the slot. If the replacement did not give anything, we use other ways. Self-tapping screws for drywall it is most often possible to unscrew applicable thin leaf rubber, Holding it between a screwdriver and slot.

When unscrewed from the board and other wooden products Effective occurs on the screw head with the subsequent tapping on the screwdriver at the time of the effort. If the screw is not fully wrapped with a semicircular head (protrudes over the surface at least per millimeter) or the design of its head allows you to do this, then you can try to pull it out of the passage or gas key.

Several droplets of the brake or lubricating fluid, kerosene will make a self-sucking scroll. You can warm the hardware, it will expand and deforms the surrounding materials, and the cooling will allow you to turn it out.

It is possible to use adhesives (superchalters, "liquid nails", "cold" welding, and if time is allowed, then epoxy compounds), soldering or if allowed parts, then welding. If the self-tapping screw did not start twist, proceed to radical measures.

Joiner's tricks. 10 methods for extracting torn screw.

Protecting faces

Regardless of the type of head and initial view Slots can be touched with a flat screwdriver. To do this, it is necessary to drench in the head, with the help of hacksaw for metal or "Bulgarian" straight slot.

It should be borne in mind that the slot depth should not exceed half the height of the head, otherwise there is a risk of its destruction. The use of diligence in conjunction with the methods listed above will increase your chances.

Use of extractors

Another way to unscrew the screws is the use of extractors. To do this, it is necessary to select the drill of the diameter of which less than the diameter of the threaded part of the screw, scroll the hole in the head, cut the left thread in it and, applying conical extractors, unscrew the methomez.

This method is suitable for filtering fasteners with all kinds of heads. But it is not suitable, to twisting the screws, because They are manufactured hardened.

There are slotted extractors that are a six-sided puck with a slot that is located on the inner channel instead of a thread. The slotted extractor dresses on the head, while the inner slot is screwed into it.

Unscrew the screws with torn faces

The screws with torn faces or with a torn cap is easiest to turn off the applied heating or by welding (if the turning force is not very large, then gluing) to the remaining part of the nut or lever or perform propyl.

How to unscrew the screws?

If all of the above results are not allowed, the fastener is very rusty, you can drill it with a drill along the metal, suitable diameter and wrap in its place larger. To drive the screws, the drill must be taken carbide. Hexagon head, practically does not break off. And with its breakdown, you can use the tips above.

Photo 1.. Twisting an old screw with a hidden head from a window sash with glass.

Of course, the easiest and fast way get rid of old screws - it's a fomka, but this method is good only when old wooden windows or doors before takeaway to the landfill or when appearance fundamental importance does not have. And to unscrew the old screw with a minimum of damage for the tree, into which it is spinning, and for glass, if the work is carried out with window sash (As shown in the photo), it often has to take the following actions:

1. Clear paint slots

Slot (from the German Schlitz - section) - this is a recess on the head (cap) of a screw for a regular or crusade screwdriver. In Soviet times, with all sorts of handles, locks and other latches on the windows and doors did not very ceremony, and therefore they shook the oil paint, not embarrassed and not paying attention to that, there is on accessories or screws protective covering or not. Well, the paint, obeying the laws of physics, accumulated in the slots and dried there, replacing his putty. Screw with 3-5 layers of paint on a secret head to unscrew without cleaning the slot is almost impossible. However, cleaned the old oil paint from the slot is not so difficult. For this, it is enough to have any sufficiently sharp metal objectMade of durable metal. Under sufficiently durable metal, not only instrumental steel is meant, but also of different kind Winged and corundum attacks on various kinds of hell, as a last resort, you can use a thin nail, in any case, its strength is much more than the strength oil paint.. Personally, I use a special wedge nozzle for these purposes, earlier this was included in a screwdriver set. Such a nozzle can not only with the wood, but also clean the slots from the paint. However, the lack of such nozzles is that it does not always happen at hand. It so happened in the described case, when it was necessary to unscrew a couple of old handles in the country, so a nail was used to clean the slots.

Cleaning the slots need very carefully, the more paint from the slots you remove, the more likely that the screw will be able to unscrew. However, this is not a guarantee of success. I don't know exactly why, if there was some kind of miscalculation in the technology of manufacture of screws, or screws for household purposes were made only on the equipment worn around in the arms race, or from low quality steel, or simply because I only come across Such old screws, but the slots in old scrutic screws are not high-quality. And the most important of their lack is that the slots are not deep. And the smaller the depth of the slot, the easier it is these the most slots "to break" or "lick" when unscrewed. After all, when we try to unscrew the screw, we must overcome the strength of friction between the core of the screw and the wood. This force arises with the elastic deformations of the wood and for many years and even decades does not weaken, and if the screw is also rust, then it is necessary to further destroy the resulting scale. And this is not always easy. Even a simple nail, scored in wood, which can immediately be pulled out with a rubbish, after many years, due to corrosion, it may be closed with the wood so that it is almost impossible to pull it out, just cut off or break.

Sometimes if there is an old unnecessary screwdriver, then you can sharpen it and use as a chisel to deepen the slots.

2. As far as possible to put pressure on the screwdriver at the very beginning of the twisting

As already mentioned, the main task is to overcome the strength of friction and the power of rust clutch, i.e. Tear the screw from the dead point. If you managed to turn the screw to at least a quarter of the turnover, then consider that the case is done, then everything will be easier. With each turn, the contact area of \u200b\u200bthe screw with the wood will decrease and the friction force will decrease. Sometimes in the process of unscrewing the slots are completely linseed completely, but if the screw is unscrewed at least on the half-meter, then the pliers can be operated.

3. Drive the screw of the screw

If the screw was scored, and not twisted in the wood and at the same time hesitated, more precisely, its axis changed the form and became not direct, then for the twisting of such a screw, it is necessary for a sufficient backlash, which can be obtained only if the twisted screw is the last. And if you raised the slots on the screw of the screw, but could not turn it even on a quarter of turnover, then in these cases optimal option - Reversing the head of the screw. To do this, you need to have a drill and a drill on metal with a diameter of a little more than the diameter of the hovering head of the screw. When you raised the slots, you can drill the head and without prior cumbers, and if the screw is stupidly not twisted, but the slots on the spot, then it is better to put it better. However, in the course of drilling, the drill will fall into tight. After the head is drilled, you can remove the accessories and the rest of the screw or unscrew the pliers or score a deeper hammer.

Probably there are other ways to twist old rusty screws, but I don't know them yet.

A very common problem when conducting construction work is the deformation of fasteners associated with the inexperience of the artist. However, sometimes even professionals are hard to figure out how to unscrew the screw with torn edges, as well as prevent the repetition of a similar situation. Let's think about the solution of this task together.

Causes of deformation of the faces

It is no secret that the outlet of a tightly fallen screw or self-pressing with torn faces of the body can take away a lot of strength, time and nerves, in view of which it is advisable to take care of the prevention of such situations in advance.

And the first to pay attention to what should be paid - this is the quality of the equipment, because it is the wear of the instrument, in most cases and becomes the cause of the "licking" of the faces of the fasteners. This is connected such a circumstance with the fact that the sting of a screwdriver or bits for the screwdriver is not sharp enough and does not provide a complete contact of the screw with the working tool. Also, such a phenomenon may be caused by the inconsistency of the applied snap-in, in view of which it is desirable to make sure that the sting of the tool is fully immersed in the fasteners' slots, thereby ensuring a strong joint.

The second reason for deformation of the faces of the screw / self-sustaining is non-compliance with the screwing technology, which in most cases is manifested in the case when the Contractor puts insufficient effort to the tool, that is, does not prescribe it properly. Either equipped (screwdriver, screwdriver) is located to the fastener at an angle. In addition, screwing screws on elevated circulation can also damage the fastener head.

The quality of the screws themselves (the type of material, the correctness of the form) also affect the correctness of their installation, in view of which the direct acquisition of fasteners should be asked by their technical characteristics.

Methods of unscrewing screws with torn edges

If the closer happened to the screw (the screwdriver or bit began to turn around, jumping around) does not need to fall into despair and began to trust the "stubborn" or even worse to score it with a hammer, and simply stop and take all possible actions to extract fasteners from Body material. Moreover, depending on the circumstances, one of the following methods can be used to solve the specified task.

Screwing screwing

First of all, you should try to remove the deformed screw standard method, carrying out his discerning. However, the specified operation follows only a high-quality tool, which may require the acquisition of an additional snap (bits, screwdrivers).

If the above-described action did not give the desired result, and the edges of the screw "merged" even more, then there will be more radical methods.

So, if the screw is screwed into the body of the material not for the entire length and the head slightly protrudes over the plane of the material, then it is possible to unscrew it with the help of the passage, the round-heads or the gas key. For which it is enough for suspicion of a plug-in tool to enhance the head of the screw and unscrew the fastener counterclockwise.

When the screw is screwed into the body completely, then without damage to the method described above, the fastener is unlikely to succeed. And as an alternative, it is advisable to use the following techniques.

Protecting faces

Allows you to ensure a screw recess of 2-3 mm, with which (using a flat screwdriver with sharp sting), you can unscrew the product. And it is quite simple to make such a slot, using a conventional metal cloth.

Cutting threads

At the professional level, the jerk can be turned off using a special device (left treadmill). For which in the fastener's body, drill a hole with a diameter of a smaller screw diameter, and already after - in the resulting hole, you should screw the extractor (counterclockwise) and when it will strive to turn the fastener.

If all of the above methods did not lead to the desired result, then the screw with torn edges is simply drilled with a drill with a metal drill.

Before unscrewing the screw with torn faces, it is advisable to get acquainted with a number of recommendations, at the expense of which the work on the removal of fasteners will be a time-consuming.

For the formation of a free gap between the self-tapping screw and the body of the material into which it is screwed, the fasteners can be heatled (for example, with the help of a soldering iron, an industrial hair dryer or lighter). In this case, in the process of heating and subsequent cooling, the screw will increase slightly, and then decrease in the amount, spreading, thus the material into which it is screwed.
