Professional Applications & Engineering Value

These black-oxide steel split lock washers deliver critical vibration-resistant performance in heavy machinery, automotive assemblies, and structural applications where 1 1/8" screw fastening requires reliable locking under constant stress. The split lock washer type standard configuration creates continuous spring tension that compensates for thermal expansion, material relaxation, and dynamic loading conditions. Engineered with Rockwell C38 hardness, these industrial washers maintain their spring properties through repeated compression cycles, preventing loosening in high-vibration environments. The black-oxide surface treatment provides corrosion resistance without compromising the steel's mechanical properties, making these ASME B18.21.1 compliant components ideal for outdoor equipment, manufacturing machinery, and transportation systems requiring durable, maintenance-free fastening solutions.

Specification Summary & Compliance

Manufactured to ASME B18.21.1 dimensional and performance standards, these split lock washers ensure precise fit with 1.153" inner diameter, 1.663" outer diameter, and 0.313" thickness specifications. The inch system measurement guarantees compatibility with North American industrial applications requiring 1 1/8" screw size fasteners. Full compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations confirms environmental safety and material restrictions adherence for international industrial use.
