The anti-theft screw, also known as the anti-removal screw, is a fastener that is designed to prevent theft of a fixed facility that has been placed in an outdoor public environment for a long time. Generally, it is divided into two types: detachable and non-removable according to the structure and type. The anti-theft screw for vehicles is a kind of detachable anti-theft screw. It can not be disassembled except for special instruments. It is worth noting that if you really want to use anti-theft screws, then please be sure to buy the original anti-theft screws. Because of the quality reasons, some anti-theft screws with poor quality may be rusted and damaged in less than two years, so I suggest everyone Don't lose it because of small size. If you change it, use the original anti-theft screw.
