What should I do if the screw is twisted and slippery?

1. Stick something hard on the edge of the slide line, then unscrew it slowly with the corresponding screwdriver, and the corresponding clip should be slowly upward, that's it!

In our daily life, we always come into contact with screws from time to time, such as bicycles, electric fans, hair dryers and other electrical appliances. But if the time is long, the screws (nuts) will often rust, and sometimes they can't be unscrewed even with a wrench. What should I do at this time?

3. Vibration: Never twist rusty screws with a wrench, so as to avoid the hexagonal edge of the screws slipping off, breaking the screws or breaking the wrench. At this time, you can gently shake the handle of the wrench with a hammer, and generally rusty screws can be shaken off.

Extended data:

To prevent slipping:

1, try to choose inner and outer hexagon or Torx-groove screws, because the contact area between inner and outer hexagon-groove screws and screw tools (screwdrivers, electric screwdrivers) is much larger than that of straight or cross-groove screws, so there is almost no slippage when using inner and outer hexagon or Torx-groove screws.

2. First, select the appropriate screw tools (screwdriver, electric screwdriver), and we will use an inappropriate tool to screw the screws with slotted and cross slots at will. For example, using a large screwdriver to screw a small head screw is easy to slip.

3, the use of appropriate strength, not the greater the strength of the screw, the better. Each screw has its own torque value, so the greater the force, not only it is easy to slip, but even the phenomenon of "broken head" will appear. If it is the kind of screw that may need to be removed frequently, improper strength or unskilled skills may also cause thread slippage.
