Professional Applications & Engineering Value
This 1/2"-13 UNC steel set screw is engineered to address critical challenges in heavy machinery, automotive assemblies, and construction equipment where vibration resistance and permanent positioning are paramount. The coarse thread spacing and Class 2A thread fit provide superior grip in soft materials or where frequent adjustments are not needed, preventing loosening under dynamic loads. Manufactured from high-strength steel with a Rockwell B80 hardness, it withstands shear forces and repetitive stress, while the square head and external square drive enable high-torque application without stripping. The cup tip concentrates pressure for secure fastening without damaging shafts or components, making it ideal for pulleys, gears, and collars in demanding industrial fastener applications.
Specification Summary & Compliance
This set screw maintains precise Class 2A thread fit per UNC standards, ensuring consistent engagement and dimensional accuracy. It is manufactured in compliance with ASME B18.6.2 specifications for square head set screws, confirming adherence to recognized engineering and safety standards. The product is also verified as RoHS 3 (2015/863/EU) Compliant and REACH (EC 1907/2006) Compliant, meeting environmental and health regulations for use in various markets.
