Professional Applications & Engineering Value

This zinc-plated steel spring lock washer delivers critical vibration resistance in industrial assemblies where constant motion and shock loads threaten joint integrity. The top serration technology creates micro-bites into mating surfaces, preventing rotational loosening that compromises equipment safety. Engineered with Rockwell C40 hardness, this component maintains its spring properties under repeated compression cycles, making it ideal for heavy machinery, automotive systems, and construction equipment where reliable fastener performance is non-negotiable. The zinc plating provides sacrificial corrosion protection, extending service life in environments exposed to moisture, chemicals, and temperature variations while the precise dimensional tolerances ensure consistent installation across production runs.

Specification Summary & Compliance

This spring lock washer features inch system dimensions with 0.323" internal diameter, 0.717" outer diameter, and thickness range of 0.052-0.058" for precise fitment with 5/16" fasteners. Manufactured to industry standards for lock washers with controlled hardness (Rockwell C40) and serration geometry. The component is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and regulatory acceptance for global industrial applications.
