Professional Applications & Engineering Value
Our bronze tooth lock washers deliver exceptional engineering value in applications where vibration-induced loosening compromises assembly integrity. The external tooth design creates multiple biting points that dig into both the fastener and mating surface, providing superior vibration resistance compared to standard washers. The bronze material with Rockwell B60 hardness offers excellent corrosion resistance while maintaining sufficient ductility to prevent embrittlement. These 5/16 inch washers are particularly valuable in heavy machinery, automotive assemblies, and industrial equipment where thermal cycling and mechanical stresses demand reliable locking solutions. The combination of material properties and tooth configuration ensures consistent performance in high-vibration environments, reducing maintenance frequency and preventing costly downtime.
Specification Summary & Compliance
This bronze tooth lock washer features precise dimensional specifications with 0.32" internal diameter, 0.61" outer diameter, and thickness ranging from 0.028" to 0.034". Manufactured to ASME B18.21.1 standards for tooth lock washers, these components ensure consistent quality and performance. The washers are fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, containing no restricted substances. Designed specifically for 5/16" screw applications in the inch system, these washers provide reliable locking performance while meeting industry-standard requirements for mechanical fasteners.
