Professional Applications & Engineering Value

This curved washer delivers critical engineering solutions where conventional flat washers fail. The zinc-plated steel construction provides essential corrosion resistance for outdoor equipment, automotive assemblies, and industrial machinery exposed to moisture and chemicals. The curved spring design maintains constant pressure on 5/16" screw connections, preventing loosening from vibration in heavy machinery, conveyor systems, and structural frameworks. Specifically engineered for 3/4" tube OD applications, it ensures proper load distribution across tubing connections, reducing stress concentrations that lead to material fatigue. The Rockwell B40 hardness guarantees the washer maintains its spring properties through repeated compression cycles, making it ideal for maintenance-heavy environments where disassembly and reassembly are frequent.

Specification Summary & Compliance

This inch-system curved washer features precise dimensional specifications including 0.33" ID, 1" OD, and 0.050-0.070" thickness range. Manufactured to industrial standards for spring washers, it provides reliable performance in vibration-resistant applications. The product fully complies with RoHS 3 (2015/863/EU) regulations and REACH (EC 1907/2006) standards, including the latest SVHC requirements updated June 2022. The zinc-plated surface treatment ensures consistent corrosion protection while maintaining the mechanical properties required for heavy-duty industrial use.
