Professional Applications & Engineering Value
Engineered for demanding industrial applications, this black-oxide alloy steel set screw solves critical challenges in machinery assembly and power transmission systems. The headless design with hex drive provides flush mounting in confined spaces while maintaining high torque capability. The Class 3A thread fit combined with UNC coarse threading ensures precise engagement in high-vibration environments, preventing loosening in automotive, manufacturing, and heavy equipment applications. The cup tip configuration creates permanent seating in shafts and collars, delivering reliable positioning for gears, pulleys, and coupling components where set screw retention is critical for operational safety and precision alignment.
Specification Summary & Compliance
Manufactured to ASME B18.3 specifications with Class 3A thread fit for precision tolerance. Features 7/16"-14 UNC coarse threads with right-hand direction and 1 3/4" length. Full compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, alongside material certification to ASTM F912 standards for consistent performance in industrial fastening applications.
