Professional Applications & Engineering Value

These 316 stainless steel split lock washers deliver critical engineering value by solving vibration-induced loosening in demanding industrial settings. The split lock design creates continuous spring tension that counters rotational forces, preventing fastener failure in machinery, structural assemblies, and processing equipment. Manufactured from corrosion-resistant 316 stainless steel, they withstand aggressive environments including chemical processing, marine applications, and food processing facilities where moisture and corrosive agents degrade ordinary fasteners. The Rockwell C35 hardness ensures the washers maintain their locking capability through repeated stress cycles, while compliance with ASME B18.21.1 standards guarantees dimensional accuracy and reliable performance across industrial maintenance and OEM applications.

Specification Summary & Compliance

This split lock washer features precise dimensional specifications with 0.512" inner diameter, 0.869" outer diameter, and 0.125" thickness, engineered for 1/2" screw applications. Manufactured to ASME B18.21.1 standards for inch-series lock washers, it ensures proper fit and function within mechanical assemblies. The product maintains full compliance with RoHS 3 (2015/863/EU) regulations and REACH (EC 1907/2006) requirements, confirming adherence to environmental safety protocols for industrial components.
