Professional Applications & Engineering Value
This M12 DIN 5406 spring lock washer delivers exceptional engineering value in applications where vibration-induced loosening compromises assembly integrity. The external tooth configuration combined with the conical spring design creates a dual-action locking mechanism that actively resorts rotational movement and maintains clamp force under sustained vibration. Manufactured from high-quality steel, this metric washer provides reliable performance in automotive assemblies, heavy machinery, and industrial equipment where secure fastening is critical. The chamfered bearing nut compatibility ensures smooth installation while the precise 12mm internal diameter guarantees perfect alignment with M12 fasteners, reducing installation time and preventing cross-threading issues in production environments.
Specification Summary & Compliance
This spring lock washer conforms to DIN 5406 standards with precise metric dimensions (12mm ID × 25mm OD × 1mm thickness) and external tooth location. The conical shape provides consistent spring action while maintaining compatibility with DIN 981 chamfered bearing nuts. Manufactured to exacting industrial specifications, the washer carries full RoHS 3 (2015/863/EU) compliance and REACH (EC 1907/2006) compliance, ensuring environmental responsibility and regulatory acceptance for international industrial applications.
