Professional Applications & Engineering Value
This split lock washer delivers critical vibration resistance in demanding industrial environments where mechanical fasteners face constant stress and movement. The passivated 18-8 stainless steel construction provides exceptional corrosion resistance, making it ideal for applications exposed to moisture, chemicals, or outdoor conditions. The precisely engineered 0.564" inner diameter ensures perfect compatibility with 9/16" screws, while the split design creates continuous spring tension that maintains clamping force under dynamic loads. These industrial washers are particularly valuable in machinery assembly, automotive manufacturing, and heavy equipment where vibration-induced loosening can lead to equipment failure or safety hazards. The combination of Rockwell C35 hardness and standardized dimensions ensures reliable performance in critical fastening systems.
Specification Summary & Compliance
This standard split lock washer features precise inch system dimensions including 0.564" ID, 0.965" OD, and 0.141" thickness, manufactured to exacting standards. The component fully complies with ASME B18.21.1 and MS35338-144 specifications, ensuring dimensional accuracy and performance reliability. Environmental compliance is confirmed through RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) adherence, meeting the latest regulatory requirements for industrial components. The passivated surface treatment on 18-8 stainless steel provides additional corrosion protection while maintaining the material's inherent strength characteristics.
