Professional Applications & Engineering Value
These M6 external tooth lock washers solve critical vibration-induced loosening problems in industrial machinery, automotive assemblies, and electrical enclosures. The zinc-plated steel construction provides both corrosion resistance and mechanical strength, while the external tooth configuration creates positive locking action that outperforms standard flat washers. The 90° countersunk design allows for seamless integration with countersunk screw heads, maintaining surface integrity in precision applications. Engineered to DIN 6798 standards, these metric lock washers deliver reliable performance in high-vibration environments where fastener security is paramount, reducing maintenance frequency and equipment downtime.
Specification Summary & Compliance
Manufactured to DIN 6798 specifications with precise dimensional tolerances: 6.4mm internal diameter, 11.8mm outer diameter, and 0.35-0.45mm thickness range. Features Rockwell C35 hardness for optimal tooth performance and 90° countersink angle for proper seating. Compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and regulatory acceptance in industrial markets.
