• Consistent hardness performance with Rockwell C35 rating maintaining tooth integrity and locking force through repeated use
• Standardized reliability meeting DIN 6797 specifications for guaranteed interchangeability and predictable performance
• Environmental compliance assurance with RoHS 3 and REACH compliance for safe use across regulated industries
• Optimized thickness range (0.8-1.0mm) providing sufficient spring action while maintaining space efficiency in assemblies

Professional Applications & Engineering Value

Our M10 external tooth lock washers deliver critical vibration resistance in demanding mechanical systems where fastener security is paramount. The zinc-plated steel construction combines corrosion protection with the mechanical strength needed for industrial applications, while the external tooth configuration ensures maximum biting action into both the fastener and workpiece surfaces. These metric lock washers are engineered to DIN 6797 standards, providing reliable performance in automotive assemblies, machinery manufacturing, and electrical equipment where vibration-induced loosening can compromise system integrity. The precise 10.5mm internal diameter and 18mm outer diameter ensure perfect compatibility with M10 fasteners, while the controlled thickness maintains consistent clamping force without adding unnecessary bulk to your assemblies.
