Professional Applications & Engineering Value

Engineered for precision motion control and rotational applications, this 18-8 Stainless Steel shoulder screw solves critical alignment challenges in industrial machinery. The 1/2" diameter shoulder with precise tolerance provides a stable bearing surface for gears, pulleys, and linkages, eliminating bushing requirements while maintaining concentricity. The passivated finish enhances corrosion resistance in humid or chemical-exposed environments, extending service life in automation equipment, conveyor systems, and packaging machinery. With 70,000 psi tensile strength and UNC coarse threads, it withstands dynamic loads while enabling rapid assembly in high-volume production lines. The socket head design with hex drive accommodates confined spaces, making it ideal for precision instruments and mechanical assemblies where reliability and repeatability are paramount.

Specification Summary & Compliance

This shoulder screw maintains Class 2A thread fit per UNC standards with precise shoulder diameter tolerance (-0.001" to 0") and shoulder length tolerance (0" to 0.002"). Manufacturing complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety. The 3/8"-16 UNC coarse thread with right-hand direction provides standardized compatibility across industrial applications.
