What should I do if the screw can t be unscrewed, what should I do if this screw can t be unscrewed?

1. When we screw the Phillips screw, if there is a problem that cannot be screwed, it may be that the screw has rusted, and if the surrounding environment is relatively humid, the screw is prone to rust when it is damp.

2. In this case, no matter how much strength we use, we will not unscrew it down, so we can first clamp the screw with a wrench, and then prepare a small hammer to hit the position of the handle, the strength is slightly larger, and a few consecutive knocks will loosen the rusty part, and then it will be much easier.

3. Because it is rusty, you can remove the rust first, there is a rust remover on the market, or there is a surplus cola at home, and pour it directly on the rusty part. Wait until it is effectively dissolved, and then use a screwdriver to turn the Phillips screws to easily unscrew.

withWrenchBuckle the screws, then hit the handle with a hammer, and wait for the rusty area to loosen and then twist.

Reasons why the screws can't be unscrewed:

1. Rust: There are generally two reasons for rust, one is that the product is dried during production, resulting in the inability to discharge internal water vapor, resulting in a chemical reaction.

As a result, rust cannot be unscrewed. Second, the use environment is too humid, and the surface of the screw cannot be screwed off due to oxidation and rust.

2. Slippery wire: improper operation or force during use, resulting in the screw slippery wire can not be unscrewed, this time it is necessary to increase the use of double-sided tape.

Gauze, 502 glue.

and other items to increase friction to come, so that the problem can be solved.

Precautions for the use of screws

1. Screw rinsing is a very important step, and no residue should be left on the surface.

2. The storage of screws should be compliant.

3. There will be a layer of white items on the surface of high-strength screws, which should be carefully checked during operation.

4. When the surface is blackened, it should be treated before use, and no impurities should remain on the surface.

5. If there is rust during rinsing, replace the rinsing water in time.

1. If the screws can't be screwed, most of them are because they have rustedAt this time, if you use brute force to twist it, it will definitely not be able to unscrew it, so it is best to use tools. Let's prepare a wrench first, then tighten the screws, and then use the hammer to hit the position of the handle, with a little more force, and hit it a few times in a row, until the rusty part of the inside is loosened, and then it may be much easier to twist.

2. If the screws have rusted,It is best to remove the rusty part first, you can go to the store to buy a remover, spray it on the rusty area, wait a little until it is fully dissolved, and then we can borrow a tool to tighten the screws, which can also be easily unscrewed.

Screws will rust.

1. If the screw is easy to rust, generally speaking, it is not completely dried during the production, resulting in water vapor inside, or there is water vapor entering when packaging after drying, and a chemical reaction will occur, resulting in the screw being easy to rust.

2. If the screw is stored in a humid place for a long time, it will slowly be corroded and oxidized, so it is easy to rust.

3. Understanding the problem that screws are easy to rust, we can prevent them, such as putting screws in a dry environment, and there should be no acidic and alkaline substances around them.

If it is too tight, you can use a hammer to pad a screwdriver to hit it, or you can use a carp plier to clamp the screw, which is also more effective.

This screw on the sewing machine is often used for loading and unloading, should not be rusted to death, really rust to die on a drop of more kerosene, use the characteristics of kerosene easy to penetrate into the gap to infiltrate the rust to loosen, and then use a screwdriver to unscrew it after a day or two. Try not to use brute force or hammering to prevent the iron rod from bending and deforming, which will affect the operation of the machinery.

Can't smash, this is a sewing machine, the presser foot including the guide rod are smashed, give a way, plug in with a large flat screwdriver, resist the wooden handle, insert it on the flat edge of the screwdriver with a trapper, and move the trap hard to unscrew it, the sewing machine belongs to high-precision equipment, and it is forbidden to knock

This thing is easy to do, you can also kick it down with a hammer, and by the way, spray a loosening agent, so that you can unscrew this screw.

Try the screwdriver in both directions and directions, or drip gasoline and it will be unscrewed!

Generally, I inject some oil into the screws first, and then I can unscrew them overnight.

It is recommended to use a syringe to add some lubricating oil and wait for a long time to get it down with a screwdriver.

Summary. Hello, I am your exclusive service technician, attentive, attentive and careful to help you solve the problem of using the car, the screw can not be screwed in, in such a situation, first check whether there is debris inside the thread of the screw, foreign objects cause damage to the thread. If the threads of the screws are not damaged, it is advisable to lubricate the threads.

A small amount of lubricating oil can be applied to the stud and then re-tightened.

What is the reason why the screws can't be screwed in after they are unscrewed?

Hello, don't worry, I can ask for your question, but wait a minute, I need text for about 2 minutes.

The screws of the seat belt cannot be screwed in after being screwed out.

Hello, I am your exclusive service technician, attentive, attentive and careful to help you solve the problem of using the car, the screw can not be screwed in, in such a situation, first check whether there is debris inside the thread of the screw, foreign objects cause damage to the thread. If the threads of the screws are not damaged, it is advisable to lubricate the threads. A small amount of lubricating oil can be applied to the stud and then re-tightened.

Check the thread to see if the thread is damaged, if the thread is not damaged, the stud must be vertically aligned with the screw hole and screw it in.

The threads are already a little damaged.

If the thread has been damaged, the thread must be repaired.

The failure to unscrew the screws is caused by a variety of reasons, such as thread rust, thread jamming, thread damage, etc. Here are some common workarounds:1

Use appropriate tools: Use the correct screwdriver or wrench to ensure that the manuscript matches the size and shape of the screw head to avoid damaging the screw head. 2.

Strengthen: Use a larger wrench or screwdriver, or use a more powerful tool, such as a wrench extension rod or pliers, to increase the force of the screw. 3.

Heating: Using a tool such as a torch or heat gun, heat the metal around the screw to expand the metal and reduce the friction of the screw pattern, making it easier to unscrew the screw. 4.

Use lubricants: Use a lubricant, such as lube or spray, and spray it on the screws to reduce friction on the threads, making it easier to unscrew the screws. 5.

Use a screw extractor: If the screw head is already damaged or stuck, you can use a screw extractor to remove the screws. A screw extractor is a tool that specializes in removing damaged screws and pulls the screw heads out of the threads.

It is important to note that care should be taken when removing the screws so as not to damage the screws or the surrounding parts due to misbalance.
