A nyloc nut, also known nylon insert lock nut, polymer insert lock nut or elastic stop nut is a kind of nut that includes a nylon collar insert.

The nylon insert locks the nut in two ways. First, it forces the bottom face of the screw threads against the top face of the nut threads, increasing the friction between the two.

Second, the nylon applies a compressive force against the screw itself. Nyloc nuts retain their locking ability up to 250°F (121°C).

The threads of the screw do not damage the nylon insert, therefore they can be reused many times.
