Professional Applications & Engineering Value

This curved washer is engineered to address common challenges in industrial assemblies, such as uneven surfaces and vibrational loosening. Made from zinc-plated steel, it provides excellent corrosion protection, crucial for outdoor or chemically exposed settings like construction, automotive, and machinery. The Rockwell B40 hardness ensures it maintains shape under load, preventing failures in high-stress applications. Its precise 1/4" screw size and 7/8" tube OD compatibility make it ideal for tubing systems, where it enhances grip and distributes forces evenly. By integrating this industrial washer, engineers can achieve reliable, long-lasting connections that reduce maintenance needs and improve overall system integrity.

Specification Summary & Compliance

This curved washer features an ID of 0.28", OD of 1", and thickness ranging from 0.050" to 0.070", adhering to standard inch measurement tolerances for precise fit. It complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and material restrictions are met. The design supports common screw and tube applications, with no specific ASME callouts, but aligns with general industrial norms for durability and performance in mechanical assemblies.
