Professional Applications & Engineering Value
This black-oxide alloy steel set screw delivers critical engineering solutions for industrial machinery, automotive components, and heavy equipment assemblies. The Class 3A thread fit combined with UNC coarse threading provides superior resistance to vibrational loosening, a common failure point in dynamic applications. The headless design with hex drive enables flush mounting in confined spaces while maintaining high torque capacity. The cup tip configuration creates concentrated contact pressure, preventing shaft migration in pulley systems, gear assemblies, and coupling applications. Manufactured to ASME B18.3 specifications, this 3/4"-10 set screw ensures dimensional consistency and reliable performance in the most demanding industrial environments.
Specification Summary & Compliance
This set screw features precision Class 3A thread fit with 3/4"-10 UNC coarse threads and right-hand thread direction. The component meets ASME B18.3 manufacturing specifications (ASTM F912) with exact dimensional tolerances. Regulatory compliance includes RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental standards, ensuring suitability for global industrial markets. The 1/2" length and 3/8" hex drive provide standardized installation across compatible applications.
