Professional Applications & Engineering Value
This M75 spring lock washer delivers critical vibration damping in heavy-duty mechanical systems where metric fasteners face constant dynamic stresses. The conical shape combined with external teeth creates a dual-action locking mechanism that prevents joint relaxation in machinery, automotive assemblies, and industrial equipment. Manufactured from high-grade steel and compliant with DIN 5406 standards, this washer maintains precise dimensional stability (75mm ID × 104mm OD) while the chamfered edge design ensures smooth installation with DIN 981 bearing nuts. The specialized tooth configuration provides maximum surface engagement without damaging components, making it ideal for applications requiring repeated disassembly and reassembly cycles.
Specification Summary & Compliance
This spring lock washer features metric dimensions with 75mm inner diameter, 104mm outer diameter, 1.5mm thickness, and 5mm overall height. Manufactured to DIN 5406 specifications with external tooth configuration and conical profile. Compatible with M75 screw sizes and DIN 981 chamfered bearing nuts. Fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations for industrial use.
