Professional Applications & Engineering Value
This square head set screw delivers exceptional engineering value in demanding industrial environments where high-strength fastening is critical. The steel construction with Rockwell B80 hardness provides excellent resistance to deformation under heavy loads, while the external square drive enables maximum torque application without stripping. The coarse UNC thread ensures quick installation and reliable holding power in machinery, equipment manufacturing, and assembly applications. The cup tip design concentrates pressure for secure component positioning, making it ideal for shaft collars, gears, and pulleys where vibration resistance is essential. This ASME B18.6.2 compliant fastener solves common industrial challenges of slippage, stripping, and inconsistent performance in high-torque applications.
Specification Summary & Compliance
This 1/2"-13 UNC square head set screw features precise Class 2A thread fit tolerance for consistent assembly performance. Manufactured to ASME B18.6.2 specifications for dimensional accuracy and mechanical properties. The fastener is fully RoHS 3 (2015/863/EU) compliant and REACH (EC 1907/2006) compliant, meeting current environmental regulations for hazardous substances. The right-hand thread direction and coarse thread spacing provide optimal performance in industrial fastening applications requiring reliable, high-strength set screws.
