Professional Applications & Engineering Value
This passivated 316 stainless steel split lock washer delivers critical vibration resistance in demanding industrial applications where fastener security is paramount. The split lock washer design generates continuous outward pressure that compensates for thermal expansion, material relaxation, and dynamic loading conditions common in machinery, automotive assemblies, and marine equipment. The Rockwell C35 hardness provides optimal spring characteristics while maintaining the exceptional corrosion resistance of 316 stainless steel, making it ideal for chemical processing, offshore operations, and food processing equipment where both vibration resistance and environmental durability are required. Engineered to ASME B18.21.1 standards, this washer ensures reliable performance in critical fastening systems where failure is not an option.
Specification Summary & Compliance
This split lock washer features precise dimensional specifications including 0.193" ID, 0.334" OD, and 0.047" thickness, engineered for No. 10 screw applications. Manufactured to ASME B18.21.1 and MS35338-138 standards, ensuring consistent quality and dimensional accuracy. The washer is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, meeting the latest environmental and safety requirements for industrial components.
