Professional Applications & Engineering Value

This M2.5 metric split lock washer delivers critical vibration-resistant performance in demanding industrial applications where loosening under dynamic loads poses significant reliability risks. The curved spring design creates continuous opposing force that compensates for thermal expansion, material relaxation, and mechanical vibrations. Manufactured from zinc-plated steel, these washers provide essential corrosion resistance for equipment exposed to moisture, chemicals, or outdoor conditions. The Rockwell C44 hardness ensures the washer maintains its spring properties without flattening or losing tension, making it ideal for precision assemblies in automotive, electronics, machinery, and aerospace applications where consistent clamping force is paramount to operational safety and longevity.

Specification Summary & Compliance

This split lock washer features precise dimensional specifications including 2.6mm internal diameter, 5.1mm outer diameter, and 0.5mm thickness, engineered to exact DIN 128A standards for dimensional accuracy and performance reliability. The product meets comprehensive regulatory requirements including RoHS 3 (2015/863/EU) compliance and REACH (EC 1907/2006) compliance with current SVHC requirements as of January 2023. Manufactured to maintain consistent mechanical properties and spring characteristics, this washer ensures reliable performance in critical fastening applications across various industrial sectors.
