Professional Applications & Engineering Value
This split lock washer delivers critical vibration resistance in demanding industrial applications where fastener security is paramount. Engineered from zinc yellow-chromate plated steel, it provides dual protection against corrosion and mechanical failure. The standard split lock washer type creates continuous spring tension that compensates for thermal expansion, vibration, and material relaxation in assembly systems. Particularly valuable in machinery, automotive, and heavy equipment applications, this washer maintains 7/16" screw integrity under dynamic loads. The precise 0.44" ID ensures proper seating while the 0.776" OD distributes clamping force effectively, preventing surface damage and maintaining joint integrity in critical connections.
Specification Summary & Compliance
This split lock washer features precise dimensional specifications including 0.44" inner diameter, 0.776" outer diameter, and 0.109" thickness, engineered for 7/16" screw applications. Manufactured to meet ASME B18.21.1 and MS35338-47 specifications, ensuring consistent performance and dimensional accuracy. The Rockwell C38 hardness provides optimal spring characteristics while maintaining durability. Constructed from zinc yellow-chromate plated steel for enhanced corrosion resistance in industrial environments.
