Professional Applications & Engineering Value
This M27 metric wedge lock washer delivers critical engineering solutions for applications where vibration-induced loosening compromises safety and performance. The zinc-flake-coated steel construction provides exceptional corrosion resistance while the dual-sided serrations create positive locking action that prevents rotational slip. Engineered with Rockwell C46 hardness, these washers maintain their structural integrity under repeated stress cycles, making them ideal for heavy machinery, construction equipment, automotive assemblies, and industrial processing systems. The wedge lock mechanism works by creating opposing forces that increase clamp load as vibration attempts to loosen the connection, effectively solving the common problem of fastener failure in dynamic environments.
Specification Summary & Compliance
This heavy-duty washer features precise dimensional specifications with 1.12" inner diameter, 1.91" outer diameter, and thickness ranging from 0.220" to 0.240" for M27 screw applications. Manufactured to exacting standards with top and bottom serrations for maximum locking effectiveness. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental responsibility and global market acceptance for industrial fastener applications requiring reliable vibration resistance and corrosion protection.
