Professional Applications & Engineering Value
This zinc-plated steel spring lock washer delivers critical vibration-resistant performance in demanding industrial and automotive applications. The top and bottom serration pattern creates superior bite force, effectively preventing fastener loosening under extreme vibration conditions that commonly plague heavy machinery, engine assemblies, and structural frameworks. The Rockwell C38 hardness rating ensures the washer maintains its locking properties through repeated stress cycles, while the zinc plating provides essential corrosion resistance in harsh operating environments. Engineered to accommodate both 5/8" and M16 screw sizes, this versatile component eliminates the need for multiple washer types in mixed-measurement assemblies, streamlining inventory and installation processes for maintenance teams and production facilities.
Specification Summary & Compliance
This spring lock washer features precise dimensional specifications including 0.669" inner diameter, 0.945" outer diameter, 0.047" thickness, and 0.083" overall height. Manufactured to exacting standards for both inch (5/8") and metric (M16) fastener systems, the component maintains consistent performance across measurement systems. The washer is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring safe usage in regulated industries and international markets.
