Professional Applications & Engineering Value
Engineered to address critical vibration-induced loosening in industrial machinery and automotive assemblies, this M5 spring lock washer delivers exceptional engineering value through its zinc-plated steel construction and curved spring design. The unique curved profile creates continuous axial pressure that compensates for thermal expansion and mechanical settling, effectively preventing fastener back-off in high-vibration environments. Meeting DIN 137A specifications, this metric lock washer provides reliable performance in electrical enclosures, motor mounts, and heavy equipment where maintaining clamp load is critical to operational safety and maintenance intervals. The combination of Rockwell C42 hardness and precise dimensional control ensures consistent spring action through repeated loading cycles.
Specification Summary & Compliance
This spring lock washer features precise metric dimensions with 5.3mm internal diameter, 10mm outer diameter, and 0.5mm thickness, manufactured to DIN 137A standards for dimensional accuracy and performance reliability. The product maintains full compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and regulatory acceptance for industrial applications across global markets.
