Professional Applications & Engineering Value
This low-profile socket head shoulder screw is engineered to address critical alignment and space constraints in precision assemblies. The 18-8 Stainless Steel material, enhanced by a passivated finish, provides excellent resistance to corrosion and wear, extending service life in demanding conditions like machinery, automotive, and electronic enclosures. The 5/8" precision shoulder acts as a reliable pivot or spacer, minimizing misalignment and reducing wear on moving parts. With a UNC coarse thread and Class 2A fit, it ensures quick, secure fastening in industrial applications, while the hex drive allows for efficient installation even in tight spaces, boosting productivity and reducing maintenance needs.
Specification Summary & Compliance
This shoulder screw adheres to UNC thread standards with a Class 2A thread fit for consistent dimensional accuracy. The shoulder features precise tolerances: diameter from -0.001" to 0" and length from 0" to 0.002". It complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and suitability for global industrial use.
