Professional Applications & Engineering Value

This M3 conical spring lock washer solves critical vibration-induced loosening in demanding industrial applications. The precision-engineered conical shape creates continuous spring tension that compensates for thermal expansion, material relaxation, and dynamic loads. Manufactured from high-strength steel with Rockwell C42 hardness, it maintains its locking properties through repeated compression cycles. The DIN 6796 standard ensures perfect compatibility with metric fastening systems in machinery, automotive assemblies, and electronic enclosures where vibration resistance is paramount. The 3.2mm ID and 7mm OD provide optimal bearing surface for M3 screw applications while the 0.6mm thickness offers space-efficient installation.

Specification Summary & Compliance

This spring lock washer features precise metric dimensions: 3.2mm internal diameter, 7mm outer diameter, and 0.6mm thickness with 0.9mm overall height. Manufactured to DIN 6796 specifications for dimensional accuracy and performance. The washer meets RoHS 3 (2015/863/EU) compliance and REACH (EC 1907/2006) regulations (updated 01/17/2023, 233 SVHC), ensuring environmental safety and regulatory acceptance for industrial use worldwide.
