Nylon Insert Lock Nuts

A hex nut with a nylon filled collar at its back end. When a screw or bolt reaches the collar, the threads and nylon form a tight frictional fit, restricting movement between the nut and bolt or screw when subjected to vibration. The nylon insert comes in various colors and is supplied with zinc plated finish. Nylon Insert Lock Nuts can be reused more times than a two-way reversible lock nut. Steel nylon insert stop nuts are less expensive than Grade C automation lock nuts. However, nylon will begin to deteriorate at temperatures from 150-350 degrees F. Thin Pattern Nylon Insert Lock Nuts allow for applications where an insufficient number of projecting threads are present to use a standard nylon insert nut. Thin pattern nylon insert nuts are intended for use in limited clearance applications and not for load bearing purposes.
