Imperial UNF Nyloc Nut

Securing critical assemblies requires hardware that stays put under heavy operation, continuous movement, and intense vibration. The Imperial UNF Nyloc Nut is engineered to provide continuous locking performance where standard hex nuts risk backing off or shaking loose over time. By incorporating a non-metallic polymer insert within the top collar, this fastener eliminates the need for external locking washers, spring washers, or chemical threadlocking compounds, simplifying assembly workflows while increasing joint reliability.

When spun onto a standard male UNF bolt or stud, the leading metal threads engage smoothly. As the bolt reaches the upper collar, the external male threads cut into the elastic nylon ring. Rather than cutting away material, the nylon deforms elastically around the mating threads, generating controlled friction and radial force across the thread contact area. This continuous prevailing torque keeps the connection firmly anchored, resisting radial play and cyclic strain.

Because the locking action relies on mechanical friction rather than chemical bonding, the UNF Nyloc Nut provides consistent holding power without seizing. It is suitable for both high-stress structural joints and precision adjustments where component alignment must remain fixed during operation. The fine thread pitch inherent to Unified Fine fasteners offers enhanced adjustment sensitivity compared to coarse alternatives, ensuring optimal clamping force across sensitive mechanical components, brackets, linkages, and frame mounts.

Built to withstand demanding workplace conditions, these nuts support quick installation using conventional tools. Whether updating machinery on the shop floor, maintaining transport fleets, or manufacturing specialized hardware, the Imperial UNF Nyloc Nut delivers a clean, professional, and dependable self-locking solution that protects equipment investments and reduces long-term maintenance overhead.
