  • Exceptional durability with Rockwell B76 hardness steel construction, resisting deformation under high-stress industrial conditions
  • Guaranteed interchangeability through strict DIN 125 standard compliance, ensuring reliable performance across metric fastener systems
  • Enhanced safety assurance with full RoHS 3 and REACH compliance, eliminating hazardous substances for workplace and environmental protection
  • Corrosion-resistant steel material maintains structural integrity in demanding environments, reducing maintenance frequency and costs
  • Optimized thickness tolerance (0.5-0.6mm) provides consistent spacing and reliable vibration resistance in precision assemblies

Professional Applications & Engineering Value

Engineered for precision metric fastener systems, these M2.5 flat washers solve critical engineering challenges in industrial applications. The steel construction with controlled Rockwell B76 hardness prevents embedding and surface damage when distributing loads across delicate components. Manufacturing facilities benefit from the DIN 125 certification which guarantees dimensional consistency for automated assembly processes, while the precise 2.7mm ID prevents misalignment in M2.5 screw applications. These metric steel washers are particularly valuable in electronics manufacturing, precision machinery, and automotive sub-assemblies where consistent thickness (0.5-0.6mm) ensures proper component spacing and reliable vibration dampening throughout the product lifecycle.

Specification Summary & Compliance

This flat washer maintains precise dimensional tolerances per DIN 125 standard with 2.7mm inner diameter, 6mm outer diameter, and 0.5-0.6mm thickness range. Manufactured from steel with Rockwell B76 hardness specification, it is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring safe integration into industrial applications worldwide while meeting rigorous quality standards for metric fastener systems.
