FAQ

Can nylon insert lock nuts be reused?
They can be reused a few times, but the nylon loses grip each time. For critical joints, use a new lock nut.

How far should the bolt stick out of a lock nut?
At least one to two full threads past the nylon ring, so the insert grips completely.

What if it gets too hot for nylon?
Above about 250°F use an all-metal prevailing torque (Stover) lock nut instead.
