Jam Nylon Insert Lock Nuts

Jam Nylon Insert Lock Nuts

Jam nylon insert Locknuts keeps fasteners in place through the nylon insert in the center of the locknut.  The nylon piece grips tightly around the threads of a fastener and prevents it from backing out or loosening.  The jam nylon insert locknut is half the height of a standard nylon insert locknut.  Add these locknuts where low clearance applications apply or behind a standard hex nut to prevent loosening.  These are reusable but the holding power decreases with each use.
