M6x1 lightweight, free-running, Keensert

Product Code: KNM6X1.0

High strength stainless steel (AISI303) solid insert. Internal thread (Class 5H): M5x0.8. External thread (Class 4H): M8x1.25. Insert length: 8mm. Price per insert. 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.

This product qualifies for next day delivery if ordered before 1pm on Monday to Wednesday.

Review by Garth
I have never been a fan of threaded inserts especially from the 90's and using helicoils.I must say this keensert may have just changed my mind. (Posted on 19/06/2018)
