Professional Applications & Engineering Value
This spring lock washer delivers critical vibration resistance in demanding industrial environments where fastener loosening can compromise safety and performance. The zinc-plated steel construction provides essential corrosion protection for outdoor equipment, automotive assemblies, and machinery exposed to harsh conditions. The unique dual serration pattern on both top and bottom surfaces creates multiple biting points that significantly enhance locking capability compared to standard washers. Engineered with Rockwell C38 hardness, this washer maintains its spring tension and serration effectiveness under repeated loading cycles, making it ideal for high-vibration applications in construction equipment, industrial machinery, and transportation systems. The dual compatibility with both 9/16" and M14 screw sizes simplifies inventory management while ensuring reliable performance across imperial and metric fastener systems.
Specification Summary & Compliance
This spring lock washer features precise dimensional specifications including 0.591" ID, 0.866" OD, 0.043" thickness, and 0.079" overall height. Manufactured from zinc-plated steel with Rockwell C38 hardness, it provides consistent performance for 9/16" and M14 screw applications. The product complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental standards, ensuring safe use in regulated industries while meeting industrial durability requirements for vibration-resistant fastening solutions.
