K-Lock Nuts

K-Lock Nuts

 

A hex nut pre-assembled with a free spinning external tooth lock washer. The locking action is achieved when the nut is tightened against a bearing surface as the teeth of the lock washer dig into it.

This is the most popular type of lock nut because of its versatility. It doesn’t gall the screw threads.
