Professional Applications & Engineering Value
This split lock washer delivers exceptional engineering value in demanding industrial environments where vibration-induced fastener failure is a critical concern. The zinc-plated steel construction combines corrosion protection with mechanical strength, while the standard split lock design creates continuous spring tension that compensates for thermal expansion and mechanical stress. The Rockwell C38 hardness ensures the washer maintains its spring characteristics under repeated loading cycles, making it ideal for heavy machinery, automotive assemblies, and structural applications where reliable vibration resistance is paramount. The precise dimensional control guarantees consistent performance across production runs, reducing maintenance costs and improving operational safety.
Specification Summary & Compliance
This split lock washer features precise dimensions with 0.984" internal diameter, 1.291" outer diameter, and 0.234" thickness, engineered for 7/8" screw applications. Manufactured to ASME B18.21.1 standards for dimensional accuracy and performance reliability. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring safe use across global industrial markets.
