Professional Applications & Engineering Value

This zinc-flake-coated steel wedge lock washer delivers critical vibration resistance in demanding industrial applications where loosening under dynamic loads poses significant safety and maintenance concerns. The unique top and bottom serration design creates a powerful locking mechanism that bites into both the fastener and mating surface, preventing rotational slip even in high-vibration environments like heavy machinery, automotive assemblies, and construction equipment. The Rockwell C46 hardness ensures the washer maintains its structural integrity under extreme clamping forces, while the zinc-flake coating provides superior corrosion resistance compared to conventional plating methods. Engineered for both 9/16" and M14 screw sizes, this washer offers versatile compatibility across inch and metric fastening systems commonly found in multinational industrial operations.

Specification Summary & Compliance

This heavy-duty wedge lock washer features precise dimensional specifications with 0.6" internal diameter, 0.91" outer diameter, and thickness ranging from 0.120" to 0.140". Manufactured from high-strength steel with zinc-flake coating and hardened to Rockwell C46, the component meets industrial standards for vibration-resistant fastening. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental responsibility and chemical safety in global industrial applications.
