These Imperial Self-Locking Hex Nuts provide a secure fastening solution for applications where vibration or movement could cause a conventional nut to loosen.

The integrated locking feature helps resist unintended loosening while retaining the convenience of a standard external hexagon drive.

Finished with a zinc-plated coating for corrosion protection, these imperial lock nuts are suitable for automotive, motorsport, machinery, fabrication, engineering, maintenance and general workshop applications.

Available in both UNC and UNF imperial thread sizes, including coarse and fine thread options.

Sold individually from Shores NZ, so you can buy exactly the quantity you need without purchasing a full box.

Important: UNC and UNF threads of the same nominal diameter are not interchangeable. Check both the diameter and thread pitch of the mating fastener before ordering.
