Professional Applications & Engineering Value

These M3 spring lock washers provide critical vibration-resistant fastening solutions for industrial equipment, automotive assemblies, and machinery where loosening under dynamic loads poses significant safety risks. The conical shape design creates continuous spring pressure that compensates for material relaxation and thermal expansion, maintaining clamp force where flat washers fail. Manufactured from zinc-plated steel, these washers offer excellent corrosion resistance while the precise metric dimensions (3.2mm ID, 7mm OD) ensure perfect fit with M3 fasteners. The Rockwell C42 hardness provides optimal spring characteristics without brittleness, making them ideal for high-cycle applications in manufacturing, electronics, and precision engineering where reliable, long-term fastening is essential.

Specification Summary & Compliance

This spring lock washer features precise metric dimensions: 3.2mm internal diameter, 7mm outer diameter, and 0.6mm thickness with conical profile. Manufactured to DIN 6796 standard specifications with Rockwell C42 hardness for consistent performance. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring safe use across various industrial applications while meeting international quality standards for spring lock washers.
