Professional Applications & Engineering Value
This split lock washer delivers critical vibration-resistant performance for heavy machinery, construction equipment, and industrial assembly applications where constant motion threatens fastener integrity. The black-oxide steel construction provides essential corrosion resistance in environments exposed to moisture, chemicals, or outdoor elements, while the Rockwell C38 hardness ensures the split lock maintains its spring tension through repeated loading cycles. Engineered to ASME B18.21.1 standards, this washer offers reliable dimensional consistency for 1 3/8" screw applications in mechanical systems, transportation equipment, and structural assemblies where vibration-induced loosening could compromise safety or operational efficiency.
Specification Summary & Compliance
This split lock washer features precise dimensions of 1.408" inner diameter, 2.219" outer diameter, and 0.344" thickness specifically designed for 1 3/8" screw applications. Manufactured to ASME B18.21.1 specifications with Rockwell C38 hardness for consistent performance. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental standards, ensuring safe use across industrial sectors while meeting international regulatory requirements for hazardous substances.
