Professional Applications & Engineering Value
This zinc-flake-coated steel wedge lock washer delivers exceptional engineering value in applications where vibration-induced loosening compromises safety and performance. The top and bottom serrations create a powerful wedge-locking effect that maintains clamp load under extreme conditions, making it ideal for heavy machinery, automotive assemblies, and industrial equipment. The Rockwell C46 hardness ensures the serrations maintain their bite through repeated stress cycles, while the corrosion-resistant coating extends service life in harsh environments. Engineered specifically for 3/8" screw applications in the inch measurement system, this washer provides a reliable solution for maintenance professionals and OEMs seeking to eliminate fastener failure in critical joints.
Specification Summary & Compliance
This wedge lock washer features precise dimensional specifications with 0.41" inner diameter, 0.65" outer diameter, and thickness ranging from 0.090" to 0.110". Manufactured from zinc-flake-coated steel with Rockwell C46 hardness, the washer provides consistent performance in inch system applications. The product maintains full compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental responsibility and global market acceptance for industrial fastening requirements.
