• Excellent corrosion resistance from bronze construction, ideal for harsh industrial environments and marine applications
• Optimal hardness performance with Rockwell B60 rating ensuring durability while maintaining necessary flexibility
• Precise dimensional compatibility with No. 3 screws through 0.102" ID and 0.235" OD for secure fastening
• Industry-standard compliance with ASME B18.21.1 specifications guaranteeing reliable performance and interchangeability
• Environmental regulation adherence with RoHS 3 and REACH compliance for global market acceptance
• Thin profile advantage with 0.010-0.016" thickness allowing use in space-constrained assemblies

Professional Applications & Engineering Value

This bronze tooth lock washer delivers exceptional engineering value in applications where vibration-induced loosening compromises assembly integrity. The external tooth configuration creates multiple biting points that dig into both the fastener and surface, maintaining clamp force in high-vibration environments like machinery, automotive systems, and electrical enclosures. The bronze material offers natural corrosion resistance without requiring additional plating, making it suitable for marine equipment, chemical processing, and outdoor applications. With Rockwell B60 hardness, these washers provide the perfect balance between bite capability and surface protection, preventing damage to softer mating materials while ensuring reliable locking performance. The ASME B18.21.1 compliance guarantees dimensional accuracy and performance consistency across industrial applications requiring No. 3 screw fastening solutions.

Specification Summary & Compliance

This bronze tooth lock washer features precise inch dimensions with 0.102" internal diameter, 0.235" external diameter, and thickness ranging from 0.010" to 0.016". Manufactured to ASME B18.21.1 specifications for tooth lock washers, it ensures proper fit and function with No. 3 screws. The external tooth location provides maximum locking effectiveness while maintaining compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, making it suitable for global industrial applications requiring restricted substance compliance.
