How to undo a small screw without a screwdriver?

Another option is to use a toothbrush. Melt one end with a lighter, and then immediately insert it into the cavity in the screw head. After waiting a bit to let the melted plastic solidify, turn the brush counterclockwise. Of course it doesn’t help if the screw is screwed too tight.

Instead of a knife, you can use a CD, if the screw is not too tight, you can unscrew it with your fingernail, a plastic bank card, a coin, or a metal ruler, a hacksaw blade and. т. д. If the screw is for a Phillips screwdriver, you need a knife with a sharp end.

Ways to remove a screw without a screwdriver

Let’s consider the most effective ways, depending on the specific type of slot. Let’s start with the Phillips head.

Option No.1. Cross slot

First, note that some screws may have one groove on the head longer than the other. If so, you should only work with a longer recess to make it easier. Let us add that the edges of these grooves can be worn away, and therefore you should work carefully, otherwise you can ruin the product.

One of the easiest ways is to use a coin. The method often works only with small screws. Insert the coin into the groove and then turn it counterclockwise.

You can try to unscrew a screw that is loose with your fingernail. Actions are the same as in the previous method.

Take the knife, place it in the cavity (long if they are different lengths) and twist it. Be careful because if the screw is tightened too much and the knife you use is of poor quality, it (the knife) can be bent without achieving the desired result.

Using a knife to drive out a Phillips head screw

Use an old CD. Place its edge in the groove and twist. The compact disk itself can be damaged by such manipulations, so make sure that you do not need it any more. Definitely the method will not help if the screw is tight.

You can saw a long groove on the head with a metal hacksaw, but this method is only effective when the hardware is not completely screwed in, t. е. if the head is slightly protruding. Hold the saw at right angles to the head and saw slowly and carefully. Then, when the groove is ready, the screw can be unscrewed with a flathead screwdriver or with improvised means (e.g. credit card).

There is a long groove in the screw head

Take a flathead screwdriver of the right size in the absence of a Phillips head screwdriver. This can only work with large/medium diameter screws. Be careful not to tear the slot edges!

Another option is to use a toothbrush. Melt one end with a lighter, and then immediately insert it into the recess on the screw head. After waiting a little for the melted plastic to solidify, turn the brush counterclockwise. Of course it does not help if the screw is screwed too tight.

Option 2. Flat spline

As noted above, there is only one cavity on the head of such a screw. If you have no flat-blade screwdriver you can use improvised means to unscrew the item. Let’s see how to do this.

Use a credit card. put it in the groove and try to turn it. Use only unnecessary card, because it can be damaged while unscrewing.

Screw out with a credit card

You can also take the “ear” of a tin can (soda pop, beer). Insert the broken off “ear” into the groove on the head of the hardware, twist.

Use a regular coin. put it in the groove and try to turn it the same way.

Screw with a coin

If the screw is not too tight, you can try unscrewing it with your fingernail. This method is not always effective for obvious reasons.

Try to unscrew the screw with a knife by inserting the blade of the latter into the groove. There is a risk of bending the blade.

Insert the blade of the knife into the recess and twist counterclockwise

The last method is to use pliers. Suitable if the screw is not completely screwed in. It is preferable to use a needle-nose pliers rather than ordinary pliers.

Option #3. Remove the Torx head screw

We are talking here about screws with a notch in the form of a hexagonal star on the head. Such screws, by the way, can be guarded screws, with the rod in the center of the star. In any case, proceed carefully, because the facets of such a slot can easily be damaged.

Try it with a flathead screwdriver. Insert its sting into the pair of opposite rays and twist gently counter-clockwise. And if the screw is guarded, the screwdriver is inserted between the rod and any of the rays, and twist in the opposite direction.

Use a small flat-blade screwdriver

To unscrew the Torx-protected screw, try using a screwdriver for the unprotected one, but then the head pin has to be removed (this can be done e.g. with a core drill and hammer).

Another possible option is to drill a hole on the tip of an ordinary screwdriver for the rod of the star.

Finally you can use the same toothbrush and melt one end with a lighter (follow the same procedure as described in the previous method).

Option #4. Remove the small screw

Let’s say right away that small screws are especially difficult to unscrew if you don’t have the proper tools at hand. Such screws are usually found in various electronic devices. Ideally, for unscrewing, tools designed for repairing glasses should be used (there will be no difficulty in finding them, and they are not very expensive). If you do not have such a device, use one of the following methods.

Table No1. How to unscrew a small screw.

Steps, photo Description
Step 1 Use a knife. place the sharp end into the slot and try to twist it. Insert the tip at a slight angle to increase the contact area.
Step 2 Use a nail file. Follow the previous method.
Step 3 If you have small, pointed scissors on hand, you can use them. But note right away that these scissors are not the best option for unscrewing screws.
Step 4 Use tweezers. Insert the sharp end into the groove and try to turn it.

Ways to unscrew screws without a screwdriver

Let’s consider the most effective ways depending on the particular type of slot. Let’s start with the Phillips.

Option #1. Phillips head slot

To begin with, note that some screws may have one recess on the head longer than the other. If so, work only with an indentation of a greater length to simplify the task. Let us add that the edges of these cavities can be abraded, and therefore you should work with care, otherwise you could damage the workpiece.

Screws with ripped edges

Flat head / half head screws (or rather splines) often come off. There are several possible causes:

  • use of old, poor quality or unsuitable tools;
  • improper screwing (e.g. with a hammer);
  • insufficient torque when unscrewing/screwing and, as a result, the screwdriver will pop out of the slot;
  • The screw is “seized” (corroded);
  • Improper use of the hardware (without drilling when necessary or for the wrong material).

Method No. 1. Unscrewing

Carefully inspect the screwdriver you use to remove the screw and change it for a better one if necessary. it is important that the stinger is firmly seated in the groove and not damaged. If replacing the screwdriver does not work, you can use other methods. If you need to e.g. drive a screw out of a piece of wood, tap the head, and then tap the tool with each pull. You can also use pliers, if possible, as we mentioned above. Or you can use a rubber band to seal it.

How to remove a screw with a torn edge

For your information! Use a few drops of either lubricant or brake fluid, or kerosene to get the screw to work. You can also heat the screw so that it expands, which deforms the surrounding material so that it can be unscrewed.

If all else fails, drastic measures can be taken.

Way #3. Extractors

Another good way to remove the screw. Select the drill so that its diameter is less than that of the threaded part of the hardware, make a hole in the head, cut a left-hand thread there and unscrew the screw with a tapered extractor. This will work for all types of heads, but in the case of self-tapping screws you’ll have to choose another method. they come hardened.

Steps of unscrewing a torn off screw with an extractor

What conclusions can be drawn? If you need to unscrew a screw with broken edges, the easiest way to do it is to weld (or glue, if the force is not too great) a nut or some kind of stop to the remaining part of the hardware, heat it and make a cut.

The manufacturers are fools who are looking for extra work

unscrew it with a regular head, then replace it with a regular bolt

I’d like to see you use an ordinary head to unscrew a Torx that’s sour or tightened with a lot of torque. On the contrary, it’s quite possible: you can hammer a Torx on an ordinary bolt with flattened edges and unscrew it.

If anything, I’ve eaten a ton of oysters.

How to unscrew a torn off sprocket bolt?

Alternatively. If the flat bar is not countersunk, you can saw a slit for a flat-blade screwdriver with a hacksaw blade and try to unscrew it that way. Before you do this, the bolt should be heated with a technical hair dryer or a soldering iron of sufficient power, it should facilitate the work. If the flat bar is big enough, you can also try to twist the bolt with the pliers, gripping it more tightly.

If the head is flat or countersunk, then everything will be much harder.

I took an appropriate flat bit from a screwdriver for this purpose, so that it fits tightly into the hexagon, gently hammered it in and then tried to pull it out with a pair of pliers.

Or better to use special extractors for unscrewing screws, they are sold as all kinds of kits or even individually.

Bolt is a fastener with an external thread.

It can consist of two elements, the threaded rod itself with the head and the nut, and can be screwed into a hole with an internal thread, that is, the nut is not on the end.

The so-called “sprocket” can be male,

If the external one (external) we need a hammer, we’ll just tap the bolt with it, but without fanaticism.

VD-40 penetrating fluid, it will make it easier to unscrew the bolt.

If not the end of the bolt nut, the same pliers hold the head, and unscrew the nut with an open-end wrench of the required size.

If “sprocket” If you have a flat screwdriver, you can make a straight cut for a flat screwdriver, you will need a hacksaw for metal, or an angle grinder with a cutting disk, or a sharp chisel, the same hammer, VD-40, screwdriver.

In the most extreme case (nothing helps), the bolt can be drilled, here you need a drill and drill bits for metal.

One more variant of unscrewing a bolt with inner sprocket, which is actually what I used.

Armed with a dremel, put a small abrasive disk on it. On the round head of the bolt with an inner sprocket, made two faces, for a ten millimeter open-end wrench. I simply filed two halves on opposite sides. Unscrewed with an ordinary wrench. This can be done with an ordinary screwdriver and even a file on the iron. In the illustration below the red areas show some of the metal being removed from the head of the bolt.

There is another way to unscrew bolts with an internal hex or sprocket, but with the facets torn off. This paste increases the adhesion of the mating parts. Pretty easy to use, does not take long to cure, adhesion is very good. the tool (Phillips screwdriver, hex or sprocket head “sticking in” into the slot perfectly). If used according to the instructions there is no paste left on the tool.

If you don’t have the right tool

Furniture suppliers deliberately make them out of fairly soft metals to save on machining. But you can still make a good repair tool for household appliances. You will only have to remove the excess part of the hex. For cutting an abrasive disc mounted on an engraver is preferable. Usually it takes no more than ¼ hour and 1-2 adjustments to make a screwdriver as good as the one in the store kit.

How to unscrew a screw that has been ripped off?

The simple method using rubber tape. It is desirable to use a wide rubber band. For a tighter fit at the head. Apply a small piece of rubber to the bit or screwdriver pressed firmly into the head of the snapped screw and unscrew it.

  • Heat and cool
  • Choose the right tool
  • Knock on the head of the bolt or screw with a hammer and an impact screwdriver
  • Use a penetrating rust remover or lubricant
  • Drill out a screw
  • Solder or weld a screwdriver or a hexagon to the screw.

What can replace an iPhone screwdriver?

The screws have tiny threads, but they are placed on the surface. Therefore, for unscrewing, you can use a knife with a thin and sharp end. Other sharp objects such as needles, scissors and awls are also used. Some people go further and use feminine jewelry.

The edges of the screw are flattened and the screw is a polyhedron. heat the phone while it is hot, apply pressure and twist the screwdriver with a flat knife while pressing the phone and keep the screwdriver pressed down. is done by two people. one presses the screwdriver, the other twists the phone so that the screw is unscrewed.

How can you tear off the slot of a self-drilling screw??

The grooves on the head of a screwdriver can be damaged for a variety of reasons, but the most common ones are:

  • ? A bad electric screwdriver bit with bevelled edges is also the reason for slotted screw breaks. Therefore, you should not use a worn out PH2 nozzle on an electric screwdriver because you may end up not being able to unscrew the screw back.
  • ? Poor-quality self-tapping screws, made with violations of standards and requirements. Metal of bad self-tapping screws, too soft and the slot can easily be damaged, even without strong force, with an electric screwdriver or an electric drill.
  • ? Excessive force applied to the electric screwdriver while tightening screws also often results in the slot being ground down. especially when the bit is wiggling on the head of the self-drilling screw, in other words, it is pressed against it vertically but with some tilt to the side.

Anyway, you can unscrew the plucked self-tapping screws.

You will need a piece of rubber or a tool such as a bolt extractor for this purpose. Even the worst versions of screws can be unscrewed with the extractor, when their flats do not have a slot in them at all.
