Professional Applications & Engineering Value

This M18 wave washer engineered from 18-8 stainless steel addresses critical industrial challenges where vibration-induced fastener failure compromises equipment reliability. The wave spring design creates consistent axial force that maintains clamp load in automotive assemblies, machinery, and electrical enclosures subject to thermal cycling and operational stresses. Unlike flat washers, the DIN 137B compliant wave profile provides predictable deflection characteristics that compensate for material relaxation and gasket compression. The corrosion-resistant stainless steel material ensures performance integrity in humid, chemical, or outdoor environments where carbon steel washers would degrade. This combination of spring functionality and durable construction makes it ideal for precision engineering applications requiring maintained preload without periodic retightening.

Specification Summary & Compliance

This metric wave washer features precise dimensions of 19mm ID × 34mm OD × 1.6mm thickness with 6.6mm overall wave height, manufactured to DIN 137B standard for dimensional consistency and spring performance. The component is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, containing no substances of very high concern as of the latest SVHC list (06/14/2023). Designed specifically for M18 screw applications, this washer delivers reliable spring force while meeting international regulatory requirements for industrial components.
