DIN 6923 | Anti-Vibration Locking Nut | NZ

Lock it once. It stays put.

The Serrated Flange Nut (DIN 6923) is a high-strength locking nut designed to resist loosening under vibration and load. Featuring integrated serrated teeth, it creates a mechanical locking effect against the surface — removing the need for separate washers.

Manufactured from steel, property class 8, and finished with zinc plating and blue passivation (A2K), these nuts offer reliable strength and corrosion resistance for automotive, fabrication, and general workshop applications.

Strong hold. No backing off. Built for real use.
