S-90464A150 0.801" ID x 1.531" OD ANSI/ABMA 8.2 Spring Lock Washers for Slotted Bearing Nuts

Key Features & Benefits at a Glance

• Superior vibration resistance through conical spring design and external teeth that bite into mating surfaces, preventing loosening under dynamic loads
• Exceptional corrosion resistance with stainless steel construction, ensuring long-term reliability in harsh industrial environments
• Precision dimensional compatibility with 0.781"-32 screws and chamfered bearing nut face styles for perfect fit and optimal performance
• Industry-standard compliance with ANSI/ABMA 8.2 specifications, guaranteeing consistent quality and interchangeability
• Enhanced assembly security through external tooth positioning that provides maximum locking action without damaging components
• Environmental responsibility with full RoHS 3 and REACH compliance, meeting strict international regulatory standards
• Optimized spring action from conical shape design that maintains constant tension and compensates for thermal expansion/contraction

Professional Applications & Engineering Value

This stainless steel spring lock washer delivers critical vibration resistance in demanding industrial applications where secure fastening is paramount. The conical shape with external teeth creates a powerful locking mechanism that prevents back-off in high-vibration environments such as machinery, automotive assemblies, and heavy equipment. Engineered specifically for 0.781"-32 screw applications with chamfered bearing nut face styles, this washer maintains constant spring tension to compensate for settlement and thermal cycling. The external tooth configuration maximizes surface contact while minimizing galling, making it ideal for repeated assembly/disassembly cycles. With ANSI/ABMA 8.2 compliance, engineers can trust consistent performance across production runs and replacement scenarios.

Specification Summary & Compliance

This spring lock washer meets ANSI/ABMA 8.2 specifications with precise dimensional tolerances including 0.801" ID, 1.531" OD, and 0.203" overall height. Manufactured from stainless steel with external tooth positioning, it's engineered for use with 0.781"-32 screws and chamfered bearing nut face styles. The product is fully RoHS 3 (2015/863/EU) compliant and REACH (EC 1907/2006) compliant, meeting the latest environmental regulations for industrial components.
