Professional Applications & Engineering Value
This black-oxide alloy steel set screw delivers critical performance advantages for precision machinery, automotive components, and industrial equipment assemblies. The Class 3A thread fit maintains tight tolerances in high-vibration environments, while the flat tip design provides maximum surface contact for secure positioning of gears, pulleys, and collars. Engineered with Rockwell C45 hardness, it resists wear and deformation under repeated torque cycles. The headless configuration with hex drive solves space-constraint challenges while ensuring reliable installation in confined areas. These UNF fine thread fasteners are particularly valuable in applications requiring precise axial positioning and minimal thread clearance.
Specification Summary & Compliance
Manufactured to ASME B18.3 specifications with Class 3A thread fit ensuring precision tolerance. Features 3/8"-24 UNF fine threads with right-hand direction and 5/8" length. Compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental standards. The black-oxide surface treatment on alloy steel substrate provides additional corrosion protection while maintaining dimensional stability.
