Q：Screws often loosen after a period of time when fixing products, how to prevent it?
A:
If the product does not need to be disassembled after installation, spot welding, riveting, gluing, and other forms can be used; If there is a need for disassembly of the product, it can be prevented from loosening by adding a flat pad or using double nuts, or by using methods such as cotter pins, stop washers, and threading steel wire ropes.
