Clamping Type | High Temperature | Anti-Vibration Locking Nut | NZ

Locks tight. Handles heat. Won’t back off.

The All Metal Lock Nut DIN 980 is a high-strength clamping nut designed to resist loosening under vibration, load, and elevated temperatures. Unlike nylon insert nuts, this design uses a metal clamping piece to create a strong mechanical locking effect — making it ideal for demanding environments.

Manufactured from property class 8 steel and finished with zinc plating and blue passivation (A2K), it delivers durability, corrosion resistance, and consistent locking performance.

No nylon. No failure. Built for serious use.
