Professional Applications & Engineering Value
This M24 metric wedge lock washer delivers critical vibration-proof security for demanding industrial applications where conventional fasteners fail. The 316 stainless steel construction provides exceptional resistance to chemical exposure, saltwater, and extreme temperatures, making it ideal for marine, chemical processing, and outdoor infrastructure. Dual top and bottom serrations create a mechanical lock that prevents loosening under cyclic loading, while the case hardened surface maintains serration sharpness through repeated use. Engineered for heavy machinery, transportation equipment, and structural assemblies, this washer solves the persistent challenge of fastener loosening in high-vibration environments, ensuring maintenance-free operation and enhanced safety.
Specification Summary & Compliance
Manufactured to precise metric dimensions with 1" ID and 1.91" OD, this wedge lock washer features controlled thickness between 0.120-0.140" for consistent performance. The case hardened treatment achieves Rockwell C51 hardness for maximum durability. Compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and material traceability. Designed specifically for M24 screw applications with dual serration technology that meets industrial locking washer performance standards.
