- UNC coarse threading facilitates quick assembly and disassembly while reducing cross-threading risks
- Headless configuration allows for flush mounting where protruding fasteners aren't feasible
Professional Applications & Engineering Value
This black-oxide alloy steel set screw delivers exceptional performance in demanding industrial applications where vibration resistance and positional security are critical. The UNC coarse thread with Class 3A fit maintains precise alignment in pulleys, gears, and collars while the 90° cone point bites deeply into shaft materials, preventing rotational slippage even under high torque loads. The Rockwell C45 hardness ensures the fastener withstands repeated adjustments without thread deformation, making it ideal for precision machinery, automotive components, and manufacturing equipment where reliable positioning is essential. The headless design with compact hex drive provides space-saving solutions for confined assemblies while maintaining full torque capability.
Specification Summary & Compliance
Manufactured to ASME B18.3 specifications and ASTM F912 standards, this set screw maintains precise Class 3A thread fit with UNC coarse thread spacing and 0.138" thread diameter. The fastener is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring safe use across global industrial markets. The right-hand thread direction and 1-1/2" length provide standardized installation across compatible applications.
