Professional Applications & Engineering Value

These M2.5 tooth lock washers deliver critical vibration resistance in precision assemblies where fastener security is paramount. The zinc-plated steel construction combines corrosion resistance with mechanical strength, while the internal tooth configuration provides maximum biting action into both bearing surfaces. This design prevents rotational slippage and maintains clamp load in industrial applications experiencing dynamic stresses, thermal cycling, or constant vibration. The DIN 6797 compliance ensures dimensional accuracy and performance reliability for European machinery, automotive subassemblies, and electronic enclosures requiring metric hardware solutions that won't compromise under operational demands.

Specification Summary & Compliance

This tooth lock washer features precise metric dimensions (2.7mm ID × 5.5mm OD) with thickness ranging 0.2-0.5mm, manufactured to DIN 6797 specifications for dimensional accuracy and performance consistency. The component demonstrates full compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and regulatory acceptance across global markets. The Rockwell C42 hardness rating confirms the material's ability to maintain structural integrity and locking functionality throughout the product lifecycle.
