S-92164A007 0.141" ID x 0.32" OD ASME B18.21.1 External-Tooth Lock Washers

Key Features & Benefits at a Glance

• Superior vibration resistance through external teeth design that bite into mating surfaces, preventing loosening under dynamic loads
• Excellent corrosion resistance provided by bronze material composition, ideal for harsh industrial environments
• Precise dimensional compatibility with No. 6 screws (0.141" ID) ensuring perfect fit and optimal locking performance
• Enhanced durability with Rockwell B60 hardness rating, maintaining tooth integrity through repeated installation cycles
• Industry-standard compliance with ASME B18.21.1 specifications, guaranteeing consistent quality and performance
• Environmental responsibility through RoHS 3 and REACH compliance, meeting strict regulatory requirements
• Reliable torque retention from external tooth configuration that distributes locking force evenly around the fastener

Professional Applications & Engineering Value

These bronze external tooth lock washers deliver exceptional engineering value in applications where vibration-induced loosening poses significant reliability concerns. The bronze material offers natural corrosion resistance while maintaining the necessary hardness (Rockwell B60) to prevent deformation under load. The external teeth configuration provides superior biting action compared to internal tooth designs, creating multiple locking points that resist rotational movement effectively. Particularly valuable in electrical connections, marine equipment, and chemical processing applications, these washers prevent galvanic corrosion when used with compatible materials while ensuring maintained clamping force in vibrating machinery, automotive assemblies, and precision industrial equipment where vibration resistance is critical to operational safety and longevity.

Specification Summary & Compliance
