Threadix key locking Insert -Keensert/Keysert

Key locking inserts are used in alloys, light materials, steel and cast iron to increase the strength of the thread in these materials. They can be used for thread repair, if the defected thread has to be replaced with the same nominal diameter.Key locking inserts are standard available in stainless steel and have 2 or 4 pre-assembled kees according to the dimensions. After installation of the kees into the parent material the assembly is form-closed. Due to these kees, key locking inserts have a positive lock against rotation and vibration. Key locking inserts give high strength joints in low strength materials.

Key locking inserts are divided in 3 major types: miniature, lightweight and heavy duty. There are always 2 versions available of a key locking insert: non-locking version and self-locking version.
