Professional Applications & Engineering Value
This 12-24 UNC set screw delivers critical engineering solutions for industrial assemblies requiring precise component positioning. The black-oxide alloy steel construction provides excellent corrosion protection in manufacturing environments, while the Rockwell C45 hardness ensures reliable performance in high-stress applications like machinery shafts, pulleys, and gear assemblies. The cup tip design concentrates pressure for superior grip on rotating components, preventing axial movement without damaging surfaces. With Class 3A thread fit and coarse UNC threading, these headless set screws offer rapid installation in tight spaces while maintaining vibration resistance. The hex drive configuration enables secure tool engagement for consistent torque application, making them ideal for precision equipment maintenance and production line applications where reliability is paramount.
Specification Summary & Compliance
This set screw maintains Class 3A thread fit per UNC standards with precise dimensional accuracy. Manufacturing complies with ASME B18.3 specifications (ASTM F912) for consistent performance. The product meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliance requirements, ensuring environmental responsibility and workplace safety standards.
