Professional Applications & Engineering Value

This M12 spring lock washer delivers critical engineering solutions where vibration-induced loosening compromises fastener integrity. The conical design creates continuous spring force that counters relaxation in bolted joints, making it ideal for automotive assemblies, heavy machinery, and electrical enclosures subject to constant motion. Manufactured from black-phosphate steel, the washer provides excellent corrosion resistance while maintaining consistent hardness. The DIN 6796 compliance ensures precise dimensional tolerances and mechanical properties for reliable performance in metric fastener systems. This combination of vibration damping, environmental protection, and standardized dimensions makes it essential for maintenance-critical applications where unscheduled downtime is unacceptable.

Specification Summary & Compliance

This spring lock washer features precise metric dimensions: 13mm internal diameter, 29mm outer diameter, and 3.0mm thickness with conical profile per DIN 6796 standard. The product maintains dimensional accuracy for Class 2A thread compatibility and is manufactured from black-phosphate coated steel for enhanced durability. Compliance includes RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and unrestricted use in industrial applications across regulated markets.
