Professional Applications & Engineering Value

These M8 conical spring lock washers deliver critical vibration-damping performance in industrial machinery, automotive assemblies, and electrical equipment where constant motion and thermal expansion threaten fastener security. The black phosphate steel construction provides essential corrosion protection while maintaining the spring tension required for permanent locking action. Unlike flat washers, the conical spring lock washer design creates continuous axial pressure that compensates for material relaxation and prevents spontaneous disassembly in high-vibration environments. Engineered to DIN 6796 specifications, these washers ensure precise dimensional control for reliable performance in metric fastener systems across manufacturing, maintenance, and OEM applications.

Specification Summary & Compliance

Manufactured to DIN 6796 standards with critical dimensions including 8.4mm ID, 18mm OD, and 2.0mm thickness for M8 screw applications. The black phosphate surface treatment provides corrosion resistance while maintaining dimensional stability. Full compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations ensures environmental responsibility and global market acceptance. These spring lock washers deliver consistent performance in industrial fastening systems requiring reliable vibration resistance and locking security.
