M3 lightweight Keensert (bag of 100 pieces)
Bag of 100 inserts.
Internal thread: M3x0.5.

Keenserts are passivated according to EN 2516 or AMS 2700. The standard product range contains metric and imperial thread dimensions. Specials are available on request. Keenserts can be used in alloys, light materials, steel and cast iron to give increased thread strength in these low strength materials. They are also used for thread repair enabling the damaged thread to be replaced with the same size thread. Keenserts give a high cycle life with multiple tightening and loosening of the bolt.
