Professional Applications & Engineering Value
This 3/8"-16 UNC square head set screw delivers critical engineering solutions for industrial fastening challenges where vibration resistance and permanent positioning are paramount. The high-strength steel construction with Rockwell B80 hardness provides exceptional resistance to deformation under torque loads, while the coarse thread design maintains gripping power in high-vibration environments common in machinery, automotive, and manufacturing equipment. The external square drive enables superior torque application compared to standard fasteners, preventing tool slippage during installation. The cup tip configuration creates concentrated surface pressure for secure shaft positioning in pulleys, gears, and collars, addressing common rotational slippage issues in power transmission systems.
Specification Summary & Compliance
This set screw features precise 3/8"-16 UNC coarse threads with Class 2A thread fit tolerance for consistent engagement and assembly efficiency. Manufacturing complies with ASME B18.6.2 specifications for dimensional accuracy and performance reliability. The product meets RoHS 3 (2015/863/EU) compliance for hazardous substance restrictions and REACH (EC 1907/2006) standards for chemical safety, ensuring suitability for global industrial applications and environmental regulations.
