Nylon Lock Nut (UNF) is a fine thread self-locking nut designed to provide secure fastening and improved resistance against loosening caused by vibration, movement, or dynamic load. It features a nylon insert inside the nut that grips the matching bolt or threaded stud, creating additional friction to help keep the nut in position after tightening.

UNF stands for Unified National Fine Thread, which is commonly used in American standard fastening systems. Compared to UNC coarse thread, UNF fine thread has a finer pitch and is suitable for applications that require better tightening control, stronger thread engagement, and more precise fastening performance.

Nylon Lock Nut (UNF) is commonly used in automotive, machinery, equipment assembly, metal fabrication, maintenance, repair, and engineering applications where secure locking and fine thread compatibility are required. It must be used with matching UNF bolts, studs, or threaded rods of the same diameter and thread pitch.
