Professional Applications & Engineering Value
This M7 wave washer delivers critical spring tension and vibration resistance in precision mechanical assemblies where constant motion and thermal cycling threaten joint integrity. The black-oxide steel construction provides essential corrosion protection while maintaining the Rockwell C42 hardness needed for consistent elastic recovery. Engineered to DIN 137B specifications, this metric wave washer solves common industrial challenges in automotive suspensions, electrical enclosures, and machinery where vibration-resistant fastening is paramount. The wave design compensates for thermal expansion and material settlement, maintaining clamp load where flat washers would fail, making it ideal for high-cycle applications requiring dependable long-term performance.
Specification Summary & Compliance
This wave washer features precise metric dimensions (14mm OD × 7.4mm ID × 0.8mm thickness) with 3mm overall height for M7 screw applications. Manufactured to DIN 137B standards with Rockwell C42 hardness material properties. Fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and unrestricted industrial use across international markets.
