Usages for Heavy Hex Steel Zinc Nylon Insert Lock Nuts

A nylon insert lock nut has a nylon collar at the top that grips the bolt threads as the bolt passes through it. That friction helps keep the nut from backing off under vibration, so the nut stays put without a separate locking washer or thread-locking compound. Heavy hex nylon insert nuts are larger across the flats and thicker than standard hex nuts, for higher-load connections. The zinc plating adds corrosion protection for indoor and general use.

Heavy Hex Steel Zinc Nylon Insert Lock Nuts for all Industries

Heavy equipment, structural and machinery assemblies, trailers, and industrial maintenance use heavy hex nylon insert nuts where a larger bearing surface and added strength are needed. Blue Ribbon Fastener supplies consistent stock.
