About Self Lock Nut (Nylock Nut)

A self lock nut (nylock nut) has a nylon ring inside the top. The ring grips the bolt thread so the nut does not loosen from vibration, without needing a spring washer or lock wire.

Where to use them

Motors, pumps, vehicles, fans, conveyors and any machine that shakes. We stock TVS self lock nuts along with MS, high-tensile and SS 304 versions, in DIN 985 (thin) and DIN 982 (regular height).

Nylon inserts are rated to about 120 °C. For hot areas such as exhausts, ask for all-metal lock nuts.

Common applications

  • Motors, pumps and vibrating machinery
  • Vehicles, tractors and two-wheelers
  • Fans, blowers and conveyors
