Professional Applications & Engineering Value
This split lock washer delivers critical vibration resistance in demanding industrial environments where fastener security is paramount. The steel construction with Rockwell C38 hardness ensures the washer maintains its spring tension and locking capability even under continuous stress cycles. The precisely engineered 0.322" ID and 0.583" OD dimensions create optimal interference fit with 5/16" screws, preventing rotational loosening in machinery, automotive assemblies, and heavy equipment. The split design allows for consistent outward pressure against both the fastener head and bearing surface, effectively dampening vibrations that would otherwise compromise joint integrity in industrial applications requiring reliable mechanical fastening solutions.
Specification Summary & Compliance
This standard split lock washer features precise inch system dimensions (0.322" ID × 0.583" OD × 0.078" thickness) specifically engineered for 5/16" screw applications. Manufactured to ASME B18.21.1 specifications with Rockwell C38 hardness for consistent performance. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring safe use across various industrial sectors while meeting international quality standards for mechanical fasteners.
