Professional Applications & Engineering Value
This heavy-duty split lock washer addresses critical vibration-induced loosening challenges in industrial applications. The zinc-plated steel construction combines corrosion resistance with mechanical strength, while the Rockwell C38 hardness ensures the washer maintains its spring tension under continuous stress. The split lock design creates constant upward force against the bolt head or nut, effectively countering rotational forces in machinery, automotive assemblies, and structural frameworks. Engineered to ASME B18.21.1 standards, this 0.512" ID washer provides reliable performance in demanding environments where vibration resistance is paramount, from manufacturing equipment to heavy machinery maintenance.
Specification Summary & Compliance
This split lock washer features precise dimensional specifications including 0.512" internal diameter, 0.869" outer diameter, and 0.125" thickness, designed specifically for 1/2" screw size applications. Manufactured to ASME B18.21.1 standards for standard lock washers, it ensures consistent performance and interchangeability. The product maintains full compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, containing no restricted substances above threshold limits as of the latest SVHC update (01/17/2023, 233 SVHC).
