Stainless Steel Lock Nuts are also known as nylon lock nuts, self-locking nuts, nylon insert lock nuts and Nyloc nuts. Nylon lock nuts are designed to increase the locking force and prevent the nut from working loose. The internal nylon ring has no threads cut into it it is forced to deform around the threads as the nut is twisted on, ensuring a tight grip on the thread.
