Product Overview

The M8 304 Stainless Steel External Tooth Lock Washer features protruding teeth that bite into surfaces to generate strong friction, effectively preventing bolt loosening in heavy machinery under vibration and heavy loads.

High corrosion resistance and strength make it ideal for industrial equipment requiring stable, long-term connections and reduced maintenance.

Key Features:

Superior Anti-Loosening: External teeth dig into mating surfaces for maximum friction and vibration resistance.

Corrosion Resistant: 304 stainless steel ensures durability in harsh environments.

Even Load Distribution: Large surface area protects substrates while maintaining tight hold.
