Professional Applications & Engineering Value
This black-oxide steel split lock washer addresses critical vibration-induced loosening challenges in industrial machinery, automotive assemblies, and heavy equipment applications. The split lock washer design creates constant spring tension against both the fastener and bearing surface, maintaining clamp load despite dynamic forces. Engineered to ASME B18.21.1 standard, this heavy-duty lock washer provides reliable performance in inch-system applications where precision fit is essential. The black-oxide surface treatment offers corrosion resistance while the Rockwell C38 hardness ensures the washer maintains its spring properties through repeated compression cycles, making it ideal for maintenance-critical applications where disassembly and reassembly are required.
Specification Summary & Compliance
This split lock washer features precise dimensional specifications including 0.385" inner diameter, 0.68" outer diameter, and 0.094" thickness, engineered specifically for 3/8" screw applications. Manufactured to ASME B18.21.1 standard for standard split lock washers, it ensures proper fit and function in inch-system assemblies. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, meeting current environmental and safety standards for industrial components.
