Professional Applications & Engineering Value
This 316 stainless steel shoulder screw is engineered to solve critical alignment and corrosion challenges in precision assemblies. The 1/2" precise shoulder acts as a reliable pivot or spacer in machinery, ensuring accurate component positioning in rotating equipment, industrial automation, and optical devices. Its UNC coarse threads provide quick assembly and superior resistance to loosening in high-vibration environments. The ultra-low socket head design maximizes space efficiency in compact engineering applications, while the Rockwell B70 hardness maintains dimensional stability under mechanical stress. Manufactured from corrosion-resistant 316 stainless steel, it delivers long-term reliability in chemical processing, marine, and food-grade equipment where material integrity is paramount.
Specification Summary & Compliance
This shoulder screw maintains Class 2A thread fit per UNC standards with precise shoulder diameter (5/32") and length (1/2") tolerances for accurate assembly. Manufacturing conforms to industrial fastener specifications for right-hand thread direction and coarse thread spacing. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring adherence to international environmental and safety standards for industrial components.
