Loksert solid keylocking inserts are used to repair damaged or worn out threads or to create new threads in original equipment. These are one piece inserts available in carbon steel and stainless steel in both metric and inch sizes.
The Loksert solid keylocking insert utilizes locking keys which provide a positive mechanical lock into the threads of the surrounding base material. The resulting thread is resistant to rotation due to vibration and torsion. These do not require any special drills or taps.
