Professional Applications & Engineering Value

These bronze split lock washers deliver exceptional engineering value in applications where vibration-induced loosening compromises safety and performance. The bronze material offers natural corrosion resistance, making these industrial washers ideal for marine, chemical processing, and outdoor equipment where moisture exposure is common. The split lock design creates continuous spring tension that compensates for thermal expansion and vibration, preventing fastener back-off in 5/16" screw applications. Engineered to ASME B18.21.1 standards, these washers provide reliable vibration resistance in heavy machinery, automotive assemblies, and industrial equipment where maintenance intervals are critical. The combination of material properties and precision manufacturing ensures consistent performance in temperature-varying environments.

Specification Summary & Compliance

This standard split lock washer features precise dimensions of 0.322" ID, 0.583" OD, and 0.078" thickness, manufactured to ASME B18.21.1 specifications for dimensional accuracy and performance reliability. The washer demonstrates full compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring safe usage across various industrial sectors.
