If the screws are used for a long time, they will inevitably slip and twist. At this time, don't use brute force, but choose the right way to deal with it. What if the screw can't be unscrewed? Why can't the screw be unscrewed? What should I pay attention to in the use and maintenance of screws? Let's take a closer look with Bian Xiao!

What if the screw can't be unscrewed?

1. Tighten the screw with a wrench, and then hit the handle with a hammer. When the rusty position is loose, you can screw it. 2. Spray welding flame on the screw, then drop a few drops of engine oil, and it can be easily unscrewed in a few minutes. 3. Spray a proper amount of rust remover on the screw, wait for a few minutes, and then tighten it after the rust dissolves.

Why can't the screw be unscrewed?

1, rust

There are generally two reasons for rust. First, the product is dry in the production process, resulting in internal water vapor can not be discharged, resulting in a chemical reaction, resulting in rust can not be unscrewed. Second, the use environment is too humid, and the screw surface cannot be unscrewed due to oxidation and rust.

2. Smooth silk

Improper operation or improper force during use causes the thread to be loosened. This time, it is necessary to add double-sided tape, gauze, 502 glue and other items to increase friction, in order to solve the problem.

What should be paid attention to when using and maintaining screws:

1, screw washing is a very important step, and no residue can be left on the surface.

2, screw storage to compliance. .

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

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

5. If the parts rust during washing, the washing water should be replaced in time.

6. When using screws, be sure to operate as required, and don't use too much force to avoid problems such as thread slipping.
