Professional Applications & Engineering Value
These zinc-flake-coated steel wedge lock washers address critical vibration-induced failure points in industrial assemblies. The dual serration technology (top and bottom) creates multiple locking points that bite into both mating surfaces, effectively resisting rotational forces and maintaining clamp load in high-vibration environments like machinery, automotive, and construction equipment. The Rockwell C46 hardness ensures the serrations maintain their bite without deforming under repeated stress cycles, while the zinc-flake coating provides superior corrosion resistance compared to standard platings, making them ideal for outdoor or chemically exposed applications. Their compatibility with both No. 10 and M5 screw sizes makes them particularly valuable for equipment manufacturers working with international standards.
Specification Summary & Compliance
Manufactured to precise dimensional specifications with 0.21" ID, 0.35" OD, and controlled thickness range of 0.060-0.080". These wedge lock washers feature dual serration design for maximum locking efficiency and are constructed from high-strength steel with Rockwell C46 hardness. Fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring safe use across industrial sectors while meeting international material safety standards.
