Professional Applications & Engineering Value
This 18-8 stainless steel split lock washer delivers exceptional engineering value in demanding industrial environments where vibration resistance is critical. The standard split lock washer design creates continuous spring tension that maintains bolt preload, preventing catastrophic failures in machinery, automotive assemblies, and electrical enclosures. The Rockwell C35 hardness ensures the washer maintains its shape and function through repeated thermal cycles and mechanical stress. Particularly valuable for No. 6 screw applications in corrosive environments, this ASME B18.21.1 certified component provides reliable performance in chemical processing equipment, marine hardware, and outdoor installations where moisture and temperature variations would compromise inferior fasteners.
Specification Summary & Compliance
This split lock washer features precise dimensional specifications including 0.148" inner diameter, 0.216" outer diameter, and 0.030" thickness, engineered for exact fit with No. 6 screws in inch measurement systems. Manufactured to ASME B18.21.1 standards for consistent quality and performance. The component is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and regulatory acceptance for industrial applications worldwide.
