Keylocking threaded inserts can be utilized to strengthen threads composed of softer metal materials, or to repair worn or stripped threads in equipment. There are several advantages to using keylocking threaded inserts in many applications. They are easy to install and provide a positive mechanical lock that prevents screw rotation. Additionally, keylocking threaded inserts can be used in almost all materials, and are also easy to remove
