Professional Applications & Engineering Value
This zinc-plated steel spring lock washer delivers critical vibration resistance in demanding industrial applications where fastener security is paramount. The dual serration technology on both top and bottom surfaces creates multiple biting edges that aggressively grip mating surfaces, preventing rotational movement and maintaining clamp force in high-vibration environments such as heavy machinery, automotive assemblies, and construction equipment. The Rockwell C38 hardness ensures the washer maintains its spring properties without deformation under repeated loading cycles. With compatibility for both 1" and M25 screw sizes, this washer provides engineering flexibility across international projects while the zinc plating offers sacrificial corrosion protection, extending service life in exposed or corrosive operating conditions.
Specification Summary & Compliance
This spring lock washer features precise dimensional specifications with 1.063" internal diameter, 1.496" outer diameter, and 0.071" thickness. The washer is manufactured to industry standards for spring lock washers with top and bottom serrations and meets Rockwell C38 hardness requirements for consistent performance. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and regulatory acceptance for industrial applications worldwide.
