Nyloc nuts online

Nyloc nut, also known nylon insert lock nut, polymer insert lock nut or elastic stop nut that contains 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. Second, the nylon forms 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.
