Professional Applications & Engineering Value
Our wedge lock washers with zinc-flake-coated steel construction and dual serrations address critical vibration-induced loosening challenges in industrial settings. The top and bottom serration design creates multiple biting surfaces that dig into both the fastener and base material, maintaining clamp load even under extreme dynamic conditions. These heavy-duty lock washers are engineered for applications where traditional flat washers fail, including heavy machinery, automotive assemblies, and structural frameworks. The Rockwell C46 hardness ensures the serrations maintain their bite through repeated stress cycles, while the corrosion-resistant coating extends service life in demanding environments. This combination of features makes them ideal for industrial applications requiring reliable, long-term fastening solutions that won't compromise under vibration or thermal cycling.
Specification Summary & Compliance
This wedge lock washer features precise dimensional specifications including 0.21" ID, 0.43" OD, and thickness ranging from 0.060" to 0.080". Manufactured from zinc-flake-coated steel with Rockwell C46 hardness, it's designed for No. 10 and M5 screw sizes in both inch and metric systems. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, meeting the latest environmental and safety standards for industrial components.
