Professional Applications & Engineering Value

This steel wave washer delivers critical engineering solutions for industrial applications where vibration resistance and consistent spring force are paramount. The wave-shaped profile creates multiple points of contact that maintain tension even under thermal expansion and mechanical stress, preventing fastener loosening in heavy-duty equipment, automotive assemblies, and machinery. Manufactured from high-grade steel with Rockwell C44 hardness, this spring washer withstands repeated compression cycles without permanent deformation. The precise 0.159" ID ensures secure fitting on No. 6, 7, and 8 screws, while the 0.375" OD provides optimal bearing surface. This industrial washer effectively addresses common challenges of joint fatigue, thermal cycling, and mechanical vibration in inch-system applications.

Specification Summary & Compliance

This wave washer features precise inch dimensions with 0.159" internal diameter, 0.375" outer diameter, and 0.012" thickness, engineered to exacting manufacturing standards. The component maintains dimensional stability across its 0.055" overall height profile. Manufactured from steel hardened to Rockwell C44 for consistent performance, this washer is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental responsibility and chemical safety in industrial applications.
