Professional Applications & Engineering Value
This 5/8" split lock washer delivers critical engineering value by preventing fastener loosening in high-vibration industrial settings. Made from zinc-plated steel, it combats corrosion in manufacturing plants, automotive assemblies, and outdoor machinery. The standard split lock design creates continuous spring tension that compensates for thermal expansion and dynamic stresses, eliminating the need for frequent retightening. With Rockwell C38 hardness, it maintains structural integrity under repeated loading cycles, making it ideal for heavy equipment, conveyor systems, and structural frameworks where vibration resistance is paramount. Its precise dimensions ensure quick installation while meeting ASME B18.21.1 standards for reliability across industrial maintenance and production lines.
Specification Summary & Compliance
This washer features inch system dimensions: 0.641" ID, 1.073" OD, and 0.156" Thickness, designed for 5/8" screw sizes. Manufactured to ASME B18.21.1 specifications with Standard split lock washer type and Rockwell C38 hardness. Fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and material restrictions adherence for global industrial supply chains.
