Professional Applications & Engineering Value

This steel wave washer is engineered to address critical challenges in industrial assemblies where vibration loosening, thermal expansion, and component wear are common. The wave spring design provides continuous axial load, compensating for gaps and maintaining bolt preload in heavy-duty applications such as automotive suspensions, machinery mounts, and electrical enclosures. Made from high-hardness steel (Rockwell C52), it withstands repeated compression cycles without fatigue, while its corrosion-resistant properties ensure longevity in humid or chemically exposed settings. By integrating precise inch dimensions (1.84" ID, 2.375" OD) and standardized compliance, this washer reduces maintenance downtime and enhances the reliability of 1 3/4" screw fastening systems.

Specification Summary & Compliance

This wave washer adheres to inch system measurement standards with an inner diameter of 1.84", outer diameter of 2.375", thickness of 0.025", and overall height of 0.168". It is manufactured to precise dimensional tolerances for consistent performance with 1 3/4" screw sizes. The washer meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliance, ensuring it is free from hazardous substances and suitable for global supply chains. Its Rockwell C52 hardness rating confirms high mechanical strength and wear resistance, aligning with industrial quality expectations for spring washers in demanding environments.
