Prevailing Torque Type Hexagon Nuts (non-metallic insert)

Nylon Insert Lock Nut or nylon lock nut, nyloc nut contains an added nylon ring within the nut that helps lock the nut into place more securely. The most popular used are nylon lock hexagon nuts which compatiable with Hexagon Head Bolts (Hex bolt).

Nylon lock nuts have a small nylon ring at one nut end that forms slightly smaller hole than the threaded hole going through the nut. When the nut is screwed onto a bolt, the bolt has to force its way through the smaller opening, causing the nylon to stretch. This stretching creates a huge amount of friction between the nut and the bolt, allowing the nut to stay tight for long periods of time without coming loose. Nylon lock nuts are especially useful for applications that involve a lot of vibration that would cause regular nuts to come loose.
