Professional Applications & Engineering Value
These tooth lock washers with internal tooth location deliver critical vibration resistance in mechanical assemblies where dynamic forces threaten joint integrity. The zinc-plated steel construction provides essential corrosion protection while maintaining the structural strength needed for industrial environments. With Rockwell C44 hardness, these washers maintain their biting action through repeated stress cycles, preventing the costly downtime associated with fastener failure. The precision-engineered dimensions (0.141" ID, 0.295" OD) ensure perfect compatibility with No. 6 screw size applications, from machinery manufacturing to electrical enclosures, where reliable locking action is non-negotiable for safety and performance.
Specification Summary & Compliance
This tooth lock washer features dimensional specifications of 0.141" internal diameter, 0.295" outer diameter, and thickness ranging 0.016-0.022". Manufactured to ASME B18.21.1 standards for dimensional accuracy and performance reliability. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental responsibility and safe use across industrial sectors.
