- Enhanced durability from Rockwell B60 hardness, maintaining tooth integrity through repeated use
- Guaranteed performance standards through full compliance with ASME B18.21.1 specifications
- Environmental compliance assurance meeting RoHS 3 and REACH regulations for global manufacturing applications
- Reliable spring action from 0.012-0.018" thickness range providing consistent tension and secure fastening
Professional Applications & Engineering Value
These bronze tooth lock washers deliver exceptional engineering value in applications where vibration-induced loosening poses significant reliability risks. The internal tooth configuration creates multiple biting points that securely anchor the fastener assembly, while the bronze material offers natural corrosion resistance without requiring additional plating or coatings. This makes them ideal for electrical components, marine equipment, and chemical processing machinery where both vibration resistance and environmental durability are critical. The Rockwell B60 hardness ensures the teeth maintain their biting capability through numerous installation cycles, providing long-term secure fastening solutions that reduce maintenance frequency and downtime in industrial operations.
Specification Summary & Compliance
This internal tooth lock washer features precise inch system dimensions with 0.115" internal diameter and 0.27" outer diameter, manufactured to ASME B18.21.1 standards for consistent performance. The component maintains dimensional accuracy within specified thickness tolerances of 0.012-0.018" and demonstrates full compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring suitability for global industrial applications requiring restricted substance control.
