Professional Applications & Engineering Value
This heavy-duty split lock washer delivers exceptional engineering value in demanding industrial environments where vibration-induced fastener failure is a critical concern. The black-oxide steel construction combined with Rockwell C38 hardness creates a robust solution that maintains its spring tension and locking capability under continuous stress. The split lock design applies constant pressure against both the fastener and bearing surface, effectively preventing back-off in machinery, heavy equipment, and structural applications. Engineered specifically for 1 1/8" screw sizes, this washer provides reliable performance in assembly lines, construction equipment, and manufacturing systems where vibration resistance is paramount to operational safety and equipment longevity.
Specification Summary & Compliance
This standard split lock washer features precise dimensional specifications with 1.153" inner diameter, 1.847" outer diameter, and 0.281" thickness, manufactured to ASME B18.21.1 standards for consistent quality and performance. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring safe use across various industrial sectors while meeting international engineering specifications for inch system washers in demanding applications.
