Professional Applications & Engineering Value
This M6 split lock washer addresses critical vibration-induced loosening challenges in mechanical assemblies. The zinc-flake coated steel material provides superior corrosion resistance while maintaining the necessary spring properties for reliable locking action. Engineered to DIN 127B standards, these washers deliver consistent performance in automotive, machinery, and equipment manufacturing applications where vibration resistance is paramount. The standard split design creates continuous spring tension against both the fastener and bearing surface, preventing rotation and maintaining clamp load in demanding environments. With Rockwell C44 hardness, these washers withstand repeated cycling without permanent deformation, ensuring long-term fastener security.
Specification Summary & Compliance
Manufactured to DIN 127B specifications with precise dimensional tolerances: 6.5mm internal diameter, 11.8mm outer diameter, and 1.5-1.7mm thickness range. The zinc-flake coated steel construction meets industry standards for corrosion protection, while the Rockwell C44 hardness ensures mechanical integrity. Compliant with RoHS and REACH environmental directives, these metric washers are designed specifically for M6 screw applications in industrial and mechanical fastening systems.
