Thread and finish compatibility

Verify that the mating bolt or stud uses a 3/8-16 thread pitch before ordering. Confirm that a zinc plated steel finish meets the corrosion resistance requirements of the application environment.

Suited for vibration prone assemblies

This lock nut suits mechanics and maintenance crews securing joints subject to movement. Buyers who need a different thread size, a non metallic material or a prevailing torque style lock nut should look at something else.
