Professional Applications & Engineering Value
This 7/16"-14 UNC steel set screw delivers critical engineering solutions where vibration resistance and permanent positioning are paramount. The cup point tip creates permanent seating by embedding into shaft materials, preventing axial movement in pulleys, gears, and collars. Manufactured from hardened steel with Rockwell B80 hardness, it maintains structural integrity under repeated stress while the coarse UNC thread ensures rapid installation and superior holding power. The external square drive accommodates standard industrial tools, providing superior torque transmission without cam-out issues. Ideal for machinery assembly, automotive components, and industrial equipment where reliable set screw performance is non-negotiable.
Specification Summary & Compliance
This fastener maintains Class 2A thread tolerances for consistent fit and performance in accordance with UNC thread standards. Manufacturing complies with ASME B18.6.2 specifications for dimensional accuracy and mechanical properties. The product meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental compliance requirements, ensuring suitability for global industrial applications without hazardous substance restrictions.
