Professional Applications & Engineering Value

This black-oxide alloy steel set screw delivers critical engineering advantages for industrial applications where vibration resistance and positioning accuracy are paramount. The Class 3A thread fit combined with fine threading (1"-14) creates superior clamping force distribution, effectively preventing loosening in high-vibration machinery, automotive assemblies, and precision equipment. The headless design with hex drive enables installation in space-constrained applications while maintaining full torque capability. The cup tip provides concentrated contact pressure without damaging shaft surfaces, making it ideal for permanent positioning of gears, pulleys, and collars on rotating components. This industrial set screw solves common fastening challenges through its right-hand UNS thread configuration and Rockwell C45 hardness, ensuring reliable performance in demanding mechanical systems.

Specification Summary & Compliance

This set screw maintains precise Class 3A thread fit tolerances with 1"-14 fine thread spacing according to UNS standards. The 2" length provides optimal engagement for various assembly requirements. Manufacturing compliance includes ASME B18.3 dimensional specifications and ASTM F912 material standards. Environmental regulations adherence covers RoHS 3 (2015/863/EU) compliance for hazardous substance restriction and REACH (EC 1907/2006) compliance for chemical safety.
