Frequently Asked Questions (FAQs)

1. What are nylon insert nuts for?

Nylon insert lock nuts—also known as nylon nuts and stop nuts—are a prevailing torque, locking nut that resists loosening caused by vibration and normal use. Unlike free spinning hex nuts, lock nuts make use of a deforming elastic or metal material to stay in position against torque and shock.

2. Which way does nylon nut go on?

Thread the nylon lock nut onto the bolt or threaded stud and turn the nut clockwise with your hand until it no longer turns. This will be the point that the nylon insert contacts the top thread of the fastener.

3. Are nylon lock nuts reusable?

Nylon insert nuts can be reused a small number of times because the mating threads only deform the nylon instead of cutting into it and permanently altering the shape. All-metal locknuts are less likely to be used more than once since the mating threads wear away this locking feature.
