Professional Applications & Engineering Value
This cadmium-plated steel split lock washer addresses critical vibration-induced loosening challenges in industrial assemblies. Engineered to ASME B18.21.1 standards, the washer's split design creates continuous spring tension that compensates for thermal expansion, material relaxation, and dynamic loads. The Rockwell C38 hardness ensures the washer maintains its spring properties under repeated stress cycles, making it ideal for heavy machinery, automotive systems, and structural applications where vibration resistance is paramount. The cadmium plating provides essential corrosion protection in demanding environments, extending the service life of both the washer and the fastened assembly while maintaining consistent locking performance.
Specification Summary & Compliance
This split lock washer features precise dimensions of 0.44" ID, 0.776" OD, and 0.109" thickness, manufactured to ASME B18.21.1 and MS35338-47 specifications. The inch system measurement ensures compatibility with standard 7/16" fasteners, while the Rockwell C38 hardness guarantees proper spring function and durability. The product meets industry standards for dimensional accuracy and performance requirements in vibration-prone applications.
