Professional Applications & Engineering Value
This stainless steel spring lock washer delivers critical vibration damping in heavy machinery, automotive assemblies, and structural applications where bolt security is paramount. The conical shape creates continuous spring tension that compensates for thermal expansion and material relaxation, while the external teeth provide immediate anti-rotation capability upon installation. Engineered specifically for chamfered bearing nuts per ANSI/ABMA 8.2 standards, this industrial washer maintains consistent preload in high-vibration environments where conventional flat washers fail. The corrosion-resistant stainless steel material ensures long-term reliability in demanding conditions including outdoor exposure, chemical processing, and marine applications.
Specification Summary & Compliance
Manufactured to ANSI/ABMA 8.2 specifications with critical dimensions of 3.8" ID, 5.219" OD, and 0.329" overall height. Designed for use with 3.730"-12 screw sizes and chamfered bearing nuts. Features external tooth location and conical spring lock washer shape for optimal performance. Compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring suitability for global industrial applications.
