Professional Applications & Engineering Value

These M3 DIN 6796 conical spring lock washers deliver critical engineering solutions for vibration-prone applications across multiple industries. The 18-8 stainless steel construction provides excellent corrosion resistance, making them ideal for automotive assemblies, electrical enclosures, and machinery subjected to moisture or chemical exposure. The conical spring design creates continuous spring force that compensates for thermal expansion, material relaxation, and vibration-induced loosening – addressing common failure points in industrial fastening systems. With precise metric dimensions (3.2mm ID, 7mm OD), these washers ensure perfect compatibility with M3 fasteners while the conical shape provides superior locking performance compared to flat washers, significantly reducing maintenance frequency and downtime in critical assemblies.

Specification Summary & Compliance

Manufactured to DIN 6796 standards with precise dimensional tolerances, these conical spring lock washers feature 3.2mm inner diameter, 7mm outer diameter, and 0.9mm overall height specifically engineered for M3 screw applications. The washers comply with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring safe use across various industrial sectors. The 18-8 stainless steel material provides consistent performance while the conical spring lock washer shape delivers reliable vibration resistance in accordance with German industrial standards.
