Heavy duty keylocking threaded insert KLTI-HD-M10-150-SS

KNHM10X1,5 Keenserts heavy duty metric type

M10x1,5 metric coarse internal thread (non-locking) and M16x1,5 external thread – 303 stainless steel

The heavy duty M10x1,5 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 M16x1,5. 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.
