Professional Applications & Engineering Value

These M3 metric tooth lock washers deliver critical vibration resistance in high-stress industrial environments where fastener security is paramount. The internal tooth location design creates multiple biting points that dig into both the fastener and mating surface, effectively preventing rotational loosening caused by machinery vibrations, thermal cycling, or dynamic loads. Manufactured from Black-Oxide Steel with Rockwell C35 hardness, these washers maintain their locking capability through repeated stress cycles without deformation. The DIN 6797 compliance ensures precise dimensional tolerances and consistent performance in automotive assemblies, industrial machinery, electrical enclosures, and precision equipment where reliable fastener retention prevents costly downtime and maintenance issues.

Specification Summary & Compliance

This precision tooth lock washer features exact dimensional specifications including 3.2mm internal diameter, 6mm outer diameter, and 0.3-0.5mm thickness specifically engineered for M3 fastener applications. Manufactured in strict accordance with DIN 6797 standards for dimensional accuracy and performance requirements. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental responsibility and chemical safety in industrial applications worldwide.
