• Excellent corrosion resistance from bronze construction, ideal for harsh industrial environments and marine applications
• Precision dimensional control with 0.089" ID and 0.2" OD ensuring perfect fit for No. 2 screws in inch system assemblies
• Durable performance backed by Rockwell B60 hardness rating for long-term reliability in high-stress applications
• Regulatory compliance assurance meeting ASME B18.21.1 standards for quality and performance verification
• Environmental responsibility with RoHS 3 and REACH compliance for safe use in regulated industries
• Optimized thickness range (0.010-0.016") providing flexibility for various assembly requirements while maintaining locking effectiveness

Professional Applications & Engineering Value

These bronze tooth lock washers deliver exceptional engineering value in applications where vibration-induced loosening compromises assembly integrity. The internal tooth location design creates multiple biting points that securely anchor the washer, maintaining constant tension and preventing back-off in dynamic environments. Made from bronze material, these washers offer natural corrosion resistance while maintaining the Rockwell B60 hardness needed for repeated disassembly and reassembly cycles. Particularly valuable in electrical connections, marine hardware, and precision instrumentation, these ASME B18.21.1 compliant washers solve the critical challenge of maintaining fastener tension in vibrating systems while providing the material compatibility needed for specialized industrial applications.
