Nylon Insert Nuts

A nylon insert nut is a type of locknut with a nylon collar insert which is engineered to resist turning. In each case, the nylon diameter is smaller than the diameter of the nut and does not have threads cut into it so that the nut is locked by friction with the plastic insert wrapping itself around the thread and locks the nut into place. Nylon insert nuts are also commonly known as elastic stop nuts, nylon-insert lock nuts and polymer-insert lock nut. Nylon Lock nuts are commonly used by mechanics and engineers when securing wheels on axles or threaded shafts.
