Professional Applications & Engineering Value
This M6 metric wave washer delivers critical engineering solutions where vibration-induced fastener failure is a primary concern. The black-oxide steel construction provides essential corrosion protection while maintaining the spring force necessary for maintaining clamp load in machinery, automotive assemblies, and electrical enclosures. The wave form design acts as a dynamic spring element that compensates for thermal expansion, material relaxation, and vibration stresses that commonly plague industrial equipment. Engineered to DIN 137B standards, these washers offer predictable performance in applications ranging from precision instruments to heavy machinery, where consistent preload and reliable vibration resistance are paramount for operational safety and reduced maintenance intervals.
Specification Summary & Compliance
This wave washer features precise dimensional specifications including 6.4mm inner diameter, 12mm outer diameter, 0.5mm thickness, and 2.6mm overall height, engineered for M6 fastener systems. Manufactured to DIN 137B standards with Rockwell C42 hardness for consistent spring performance. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, meeting current environmental standards for industrial components.
