Professional Applications & Engineering Value
This 1/2"-13 UNC thread set screw delivers critical engineering solutions for industrial applications requiring secure axial positioning of components on shafts, spindles, and rotating assemblies. The steel construction with Rockwell B80 hardness provides the necessary strength to prevent stripping and maintain clamping force in high-stress environments. The coarse UNC thread offers rapid installation while the square head with external square drive enables high-torque application without cam-out issues. The cup tip design creates concentrated pressure points that dig into mating surfaces, solving common problems of component slippage in machinery, automotive, and heavy equipment applications where vibration resistance is paramount.
Specification Summary & Compliance
This set screw maintains Class 2A thread fit tolerance per UNC standards, ensuring precise engagement with mating components. Manufacturing complies with ASME B18.6.2 specifications for dimensional accuracy and performance requirements. The product meets RoHS 3 (2015/863/EU) compliance for restricted hazardous substances and REACH (EC 1907/2006) regulations for chemical safety, making it suitable for global industrial supply chains and environmentally conscious manufacturing operations.
