Heavy duty keylocking threaded insert KLTI-HD-M4-070-LSS

KNHML4X0,7 Keenserts heavy duty metric locking type

M4x0.7 metric coarse internal thread (locking) and M8x1.25 external thread – 303 stainless steel

The heavy duty M4 x 0,7 keylocking insert results in an increased thread strength in low strength materials such as alloys or other light materials. The external thread of this insert is M8 x 1,25. This insert can also be used in steel and cast iron.

Although these type of inserts are typically used in a production environment, they are also popular as a high quality thread repair solution to replace a damaged thread with the same size thread.
