Professional Applications & Engineering Value
This aluminum split lock washer delivers critical vibration-dampening performance where weight reduction and corrosion resistance are essential. The split lock washer type: standard design creates continuous spring tension against both the bearing surface and fastener head, effectively preventing back-off in machinery, automotive assemblies, and electrical enclosures. Made from aluminum material, it eliminates galvanic corrosion concerns when paired with compatible metals while providing excellent conductivity for grounding applications. The Rockwell B87 hardness ensures the washer maintains its spring properties through repeated compression cycles, making it ideal for maintenance-intensive environments where frequent disassembly is required. Engineered to ASME B18.21.1 standards, this washer guarantees dimensional consistency and reliable performance across your fastener systems.
Specification Summary & Compliance
This split lock washer features precise inch system dimensions with 0.512" inner diameter, 0.869" outer diameter, and 0.125" thickness, specifically engineered for 1/2" screw applications. Manufactured to ASME B18.21.1 specifications, it ensures dimensional accuracy and performance reliability. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, meeting the latest environmental and safety standards for industrial components.
