• Global compliance assurance meeting both RoHS 3 and REACH environmental standards

Professional Applications & Engineering Value

This steel wave washer delivers critical engineering solutions where vibration resistance and spring tension are paramount. The 0.45" inner diameter precisely accommodates 7/16" fasteners while the 0.75" outer diameter provides optimal bearing surface distribution. Manufactured from hardened steel with Rockwell C44 rating, this washer maintains its mechanical properties under repeated compression cycles, preventing relaxation common in inferior spring washers. The wave configuration offers consistent axial load compensation in assemblies subject to thermal expansion, mechanical shock, or operational vibrations. Ideal for industrial machinery, automotive assemblies, and heavy-duty equipment where reliable preload maintenance is essential for operational safety and reduced maintenance intervals.

Specification Summary & Compliance

This inch-system wave washer features precise dimensional specifications: 0.45" ID, 0.75" OD, 0.015" thickness, and 0.09" overall height. Manufactured to exacting standards with Rockwell C44 hardness ensuring consistent performance. The product is fully RoHS 3 (2015/863/EU) compliant and REACH (EC 1907/2006) compliant with current SVHC requirements, meeting international environmental and safety regulations for industrial components.
