Professional Applications & Engineering Value
This split lock washer is engineered to solve critical vibration-induced loosening in industrial fastening systems. Constructed from 18-8 Stainless Steel, it provides exceptional corrosion resistance for applications in manufacturing, machinery, and outdoor equipment where moisture and chemicals are present. The standard split lock design creates continuous spring tension that compensates for thermal expansion, material relaxation, and dynamic stresses. With its precise 0.174" ID specifically sized for No. 8 screws, this washer delivers reliable performance in assembly lines, electrical enclosures, automotive components, and other vibration-prone environments where fastener security is paramount to operational safety and maintenance reduction.
Specification Summary & Compliance
This split lock washer features dimensional specifications of 0.174" ID, 0.307" OD, and 0.047" thickness, manufactured to ASME B18.21.1 standards for consistent performance and interchangeability. The washer maintains Rockwell C35 hardness for optimal spring properties and meets comprehensive compliance requirements including RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and regulatory adherence for global industrial applications.
