Professional Applications & Engineering Value
Engineered for demanding industrial applications, these 18-8 stainless steel split lock washers provide critical vibration-resistant locking where fastener security is paramount. The split lock design creates continuous spring tension that compensates for thermal expansion, vibration-induced loosening, and material relaxation in machinery, automotive assemblies, and electrical enclosures. The corrosion-resistant properties of 18-8 stainless steel make these washers ideal for outdoor equipment, marine environments, and chemical processing facilities where moisture and corrosive elements are present. With precise 0.12" inner diameter matching No. 4 screw specifications, these washers ensure secure fastening in tight-tolerance applications while maintaining ASME B18.21.1 standard compliance for reliable performance across industrial maintenance and manufacturing operations.
Specification Summary & Compliance
This standard split lock washer features precise dimensional specifications including 0.12" ID, 0.173" OD, and 0.022" thickness, engineered to exact ASME B18.21.1 manufacturing standards. The washer maintains Rockwell C35 hardness for optimal spring performance and meets comprehensive compliance requirements including RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental responsibility and workplace safety standards are fully addressed for global industrial applications.
