Nylon Insert Heavy Hex Lock Nuts

Heavy Lock Nuts with a Nylon Insert in Zinc Plated Steel

A lock nut used for fastening to a bolt when mechanically joining materials together. The nylon material located at the top of the nut prevent loosening from vibration or back off. The insert deforms elastically over the threads of the screw, but threads are not cut into the nylon. The nylon insert locks the nut in two ways. First, it forces the bottom face of the screw threads against the top face of the nut threads, increasing the friction between the two. Second, the nylon applies a compressive force against the screw itself. Nyloc nuts retain their locking ability up to 250 °F (121 °C). Heavy nylon insert lock nuts are thicker than standard nylon lock nuts, making them more suited for heavy-duty applications.

Heavy nylon insert lock nuts in this selection are case-hardened (CR+3) Zinc Plated Grade A Steel. This adds a layer of protection and durability to the fastener.
