Professional Applications & Engineering Value
This spring lock washer delivers critical vibration resistance in demanding industrial environments where fastener security is paramount. The zinc-plated steel construction provides essential corrosion protection while maintaining structural integrity under repetitive stress cycles. The innovative dual serration design on both top and bottom surfaces creates maximum bite and anti-rotation capability, effectively preventing loosening in machinery, heavy equipment, and structural applications. With compatibility for both 1 3/8" and M36 screw sizes, this washer offers versatile solutions for maintenance teams working with mixed measurement systems. The Rockwell C38 hardness ensures the washer maintains its spring properties and serration effectiveness through repeated compression cycles, making it ideal for automotive, construction, and manufacturing applications where reliability cannot be compromised.
Specification Summary & Compliance
This heavy-duty spring lock washer features precise dimensional specifications including 1.496" ID, 2.126" OD, 0.098" thickness, and 0.165" overall height. Manufactured from zinc-plated steel with Rockwell C38 hardness, it is engineered for compatibility with 1 3/8" and M36 screw sizes. The product fully complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental responsibility and global market acceptance for industrial applications requiring reliable vibration-resistant fastening solutions.
