Professional Applications & Engineering Value
This M12 DIN 462 spring lock washer delivers exceptional engineering value in vibration-prone industrial environments where fastener security is critical. The conical steel construction creates continuous spring tension that compensates for material relaxation and thermal cycling, effectively preventing loosening in machinery, automotive assemblies, and heavy equipment. The stepped bearing nut face compatibility (DIN 1804) ensures positive engagement with mating components, eliminating rotational slip while the metric dimensions (12mm ID × 28mm OD) provide precise fit for M12 fastening systems. This spring lock washer solves common industrial challenges of maintenance reduction and assembly integrity in dynamic loading conditions.
Specification Summary & Compliance
Manufactured to DIN 462 standards with precise metric dimensions: 12mm internal diameter, 28mm outer diameter, 0.8mm thickness, and 3mm overall height. Features stepped bearing nut compatibility per DIN 1804 specifications. Fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring suitability for global industrial applications and restricted substance requirements.
