Professional Applications & Engineering Value
This black-oxide alloy steel set screw delivers exceptional performance in heavy-duty industrial applications where vibration resistance and permanent positioning are critical. The Class 3A thread fit provides superior dimensional accuracy for precise component alignment in machinery, automotive assemblies, and manufacturing equipment. The headless design with hex drive allows installation in confined spaces while maintaining high torque capability. The cup tip configuration creates concentrated pressure points that prevent slippage in rotating components, shafts, and collars. With Rockwell C45 hardness and corrosion-resistant black-oxide finish, these UNC coarse thread set screws withstand harsh operating conditions while maintaining their clamping force integrity over extended service periods.
Specification Summary & Compliance
Manufactured to exacting ASME B18.3 standards with Class 3A thread fit precision for superior dimensional control. Features 5/8"-11 UNC coarse threads with right-hand direction and 2-3/4" length. Full compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring safe use across industrial sectors. The black-oxide surface treatment on alloy steel substrate provides consistent corrosion protection while maintaining the Rockwell C45 hardness required for high-strength fastening applications.
