Professional Applications & Engineering Value
This M10 spring lock washer delivers critical vibration-dampening performance for industrial machinery, automotive assemblies, and heavy equipment where constant tension maintenance prevents fastener loosening. The curved spring design creates continuous axial pressure that counters rotational forces and thermal cycling effects. Manufactured from zinc-plated steel, it provides essential corrosion resistance while maintaining the Rockwell C42 hardness necessary for repeated compression cycles. The DIN 137A certification ensures precise dimensional tolerances for reliable metric fastener systems in applications demanding consistent clamping force and long-term joint integrity without maintenance interventions.
Specification Summary & Compliance
This washer meets DIN 137A specifications with precise metric dimensions: 10.5mm internal diameter, 18mm outer diameter, 0.8mm thickness, and 4mm overall height, engineered for M10 screw applications. The zinc-plated steel construction provides corrosion protection while maintaining Rockwell C42 hardness for optimal spring performance. Compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and unrestricted use across global industrial markets.
