Screw Lock Insert

Screw lock insert is a polygonal locking ring that adds one or more turns to the common type of screw sleeve. The elasticity of the locking ring has a braking effect on the screw. Screw lock insert has all the advantages of the ordinary type wire screw sleeve, does not affect the screw installation, and only adds appropriate torque during installation. Screw lock insert wire can lock the screw in the threaded hole, so that the screw can not be loosened when it is subjected to vibration and impact, which is better than the normal locking device. Screw lock insert has multiple times of disassembly without reducing the torque of the thread, and also has high reusability.
