Professional Applications & Engineering Value

This M2.5 metric spring lock washer delivers critical vibration-resistant performance in demanding industrial applications where fastener loosening can compromise system integrity. The conical spring washer design creates continuous axial force that counters vibrational stresses in machinery, automotive assemblies, and precision equipment. Manufactured from 18-8 stainless steel, this DIN 6796 compliant washer maintains its spring properties and corrosion resistance even in humid or chemically aggressive environments. The Rockwell C35 hardness ensures the conical shape retains its tension characteristics through repeated compression cycles, making it ideal for applications requiring reliable, long-term fastening security without frequent maintenance or replacement.

Specification Summary & Compliance

This spring lock washer features precise metric dimensions: 2.7mm inner diameter, 6mm outer diameter, 0.5mm thickness, and 0.7mm overall height, specifically engineered for M2.5 screw applications. The product strictly conforms to DIN 6796 standards for dimensional accuracy and performance requirements. Manufacturing compliance includes RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and restricted substance compliance for global industrial applications.
