Professional Applications & Engineering Value

This M14 wave washer engineered with Black-Oxide Steel addresses critical challenges in industrial machinery where vibration-induced fastener failure is a common concern. The wave spring design creates persistent axial force that maintains bolt preload, effectively preventing spontaneous loosening in motors, pumps, and transmission systems. With Rockwell C42 hardness, it withstands repeated compression without permanent deformation, ensuring long-term reliability in automotive, manufacturing, and heavy equipment applications. The DIN 137B standard compliance provides engineers with predictable performance metrics for precise calculations in metric assembly projects, while the black-oxide surface treatment resists corrosion in environments with moderate exposure to moisture and chemicals.

Specification Summary & Compliance

This wave washer features precise metric dimensions with 15mm ID × 28mm OD and 1.6mm thickness, manufactured to DIN 137B specifications for dimensional consistency. The Black-Oxide Steel construction provides both corrosion protection and aesthetic finish. Compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations ensures environmental safety and unrestricted use across industrial sectors. Designed specifically for M14 screw sizes, this component delivers reliable performance in applications requiring controlled spring tension and vibration damping.
