- Exceptional durability with Rockwell C46 hardness rating for long-term performance
- Dual-standard compatibility working with both 9/16" and M14 screw sizes for design flexibility
- Precise dimensional control with 0.120-0.140" thickness ensuring consistent performance
- Environmental compliance meeting RoHS 3 and REACH standards for global industrial applications
Professional Applications & Engineering Value
Our zinc-flake-coated steel wedge lock washers deliver critical vibration resistance in demanding industrial environments where traditional fasteners fail. The dual serration technology (top and bottom) creates multiple biting surfaces that prevent rotational loosening under dynamic loads, making them ideal for heavy machinery, automotive assemblies, and structural applications. The Rockwell C46 hardness ensures the serrations maintain their grip without deformation, while the corrosion-resistant coating protects against environmental degradation. These wedge lock washers provide reliable performance for both inch (9/16") and metric (M14) fastener systems, offering engineers flexibility in global equipment design while solving persistent vibration-induced fastener failure issues.
Specification Summary & Compliance
This wedge lock washer features precise dimensions with 0.6" ID, 1.21" OD, and 0.120-0.140" thickness range, engineered for optimal performance with 9/16" and M14 screw sizes. Manufactured to industrial standards with Rockwell C46 hardness for consistent locking force. 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 applications requiring reliable vibration-resistant fastening solutions.
