Professional Applications & Engineering Value

This M12 spring lock washer delivers critical vibration resistance in demanding industrial applications where loosening under dynamic loads poses significant safety and maintenance concerns. The conical design creates continuous spring tension that compensates for material settlement and thermal expansion, making it ideal for heavy machinery, automotive assemblies, and construction equipment. Manufactured from zinc-plated steel, it provides excellent corrosion resistance while maintaining the Rockwell C42 hardness necessary for high-stress environments. The precise 13mm ID and 29mm OD dimensions ensure proper seating and load distribution, preventing surface damage and maintaining joint integrity. This DIN 6796 compliant washer solves common fastener failure issues in vibration-prone applications, reducing maintenance frequency and improving operational safety.

Specification Summary & Compliance

This spring lock washer features precise dimensional specifications with 13mm inner diameter, 29mm outer diameter, and 3.0mm thickness, engineered to DIN 6796 standards for consistent performance and interchangeability. The conical shape provides optimal spring action with 4mm overall height, while the Rockwell C42 hardness ensures mechanical durability. Manufacturing compliance includes RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming environmental responsibility and chemical safety for industrial applications worldwide.
