Professional Applications & Engineering Value
This 5/16"-24 UNF Class 3A set screw is engineered to address critical challenges in industrial assembly, such as component misalignment and vibration-induced failures. Made from 18-8 stainless steel, it offers excellent resistance to rust and corrosion, making it suitable for applications in moist or chemically aggressive environments. The fine thread spacing and Class 3A thread fit provide tight tolerances, enhancing grip and reducing the risk of loosening in high-vibration settings like automotive, aerospace, and machinery. The headless design with hex drive allows for flush mounting, saving space and improving safety in compact assemblies. Coupled with a cup tip, it ensures maximum contact and holding force, preventing slippage in precision equipment and heavy-duty fixtures.
Specification Summary & Compliance
This set screw adheres to ASME B18.3 specifications, with precise Class 3A thread fit for accurate engagement. It meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliance, ensuring environmental safety and regulatory adherence. Dimensions include a 2-1/4" length, 5/16"-24 UNF fine threads, and right-hand thread direction, providing reliable performance in standardized industrial applications.
