Lock Nut (Nylon Insert, DIN985) is a self-locking hex nut designed to help prevent loosening caused by vibration, movement, and dynamic load. Also known as a Nyloc Nut, Nylon Lock Nut, or Nylon Insert Hex Lock Nut, it features a nylon insert at the top section of the nut that grips the mating bolt, screw, stud, or threaded rod after tightening.

The nylon insert creates additional friction on the thread, helping the nut maintain its fastening position better than a standard hex nut in vibration-prone applications. This makes Lock Nut (Nylon Insert, DIN985) suitable for machinery, automotive, construction, metal fabrication, equipment assembly, repair work, and general industrial maintenance applications.

DIN985 Nylon Insert Lock Nut is commonly used where secure fastening, easy installation, and anti-loosening performance are required. It must be used with a compatible bolt, screw, stud, or threaded rod of the correct size and thread pitch.
