Professional Applications & Engineering Value

This M12 conical spring lock washer delivers exceptional engineering value in demanding industrial environments where vibration-induced loosening compromises equipment reliability. The Black-Oxide 18-8 Stainless Steel construction provides superior corrosion resistance while maintaining the necessary spring properties for continuous locking force. The conical design ensures progressive deflection that maintains tension even as components settle, making it ideal for heavy machinery, automotive assemblies, and industrial equipment subject to dynamic loads. Meeting DIN 6796 standards guarantees precise dimensional accuracy and consistent performance across applications, while the Rockwell C35 hardness ensures the washer maintains its spring characteristics through repeated compression cycles without permanent deformation.

Specification Summary & Compliance

This conical spring lock washer features precise metric dimensions with 13mm internal diameter, 29mm outer diameter, and 3.0mm thickness, engineered specifically for M12 screw applications. Manufactured to DIN 6796 specifications ensuring dimensional accuracy and performance reliability. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental standards, containing no substances of very high concern above threshold limits. The Black-Oxide surface treatment on 18-8 Stainless Steel provides additional corrosion protection while maintaining the material's inherent strength and durability characteristics.
