Category: Self-locking Screws

The threads of self-locking screws are precisely angled so that, once the screw is placed, they will not slip or move unless some additional force is applied. After you have screwed a self-locking screw into position, it will not move again unless you use a screwdriver or similar tool to remove it from position. You will have to use force to unscrew a self-locking screw even with the proper tool; they are designed to stay in place.
