In our daily life, we often encounter the phenomenon of nut slippage. The bolt manufacturer tells you what to do in this situation? When there is no professional equipment or lack of experience, screw twisting (also known as slippery wire) often occurs, so today maijin introduces several rescue methods: (1) Put something on the top of the screwdriver head, such as double-sided tape, non-proof cloth, etc. If you really have no conditions, printing paper can be used. This can increase the magnitude of friction. (2) Use a little 502 superglue to introduce the screw hole, and then screw the screw in. After the superglue solidifies, use the diagonal pliers to unscrew the screw (you don't need a screwdriver because the screw will slip). Wait until the superglue is completely hardened. (3) The bolt manufacturer pointed out that the screw cap is exposed. You can use needle-nose pliers to tighten the screw cap and then unscrew the screw. You can also cut off the screw cap, and then solve it after disassembling the shell. It takes a professional to do it. (4) Generally, the screws of mobile phones are made of metal, and the casing is made of plastic. If they cannot be unscrewed, you can use a pointed electric soldering iron tip to insert into the screw cap, heat the metal screw to melt the plastic around the screw, clamp it with needle-nose pliers, and pull it out gently! You can also forcefully press the screw up and down by 1mm (be careful not to penetrate the casing), and the problem of screw loosening can be solved. (5) Such a small screw is really difficult to fix. My dad used to repair bicycle screws. He used a small electric drill to drill a not-deep hole in the middle of the threaded screw, and then screwed in a reversed internal thread (the internal thread must be reversed, it is difficult to find. You have to go to a larger measuring instrument tool shop), and then you can twist it open.
