Professional Applications & Engineering Value
This 1/2"-13 UNC set screw with steel construction and cup point design addresses critical engineering challenges in industrial settings. The coarse thread spacing combined with Class 2A thread fit ensures rapid installation and secure fastening in machinery, automotive components, and power transmission systems. The Rockwell B80 hardness provides exceptional resistance to deformation under high clamping forces, while the external square drive prevents cam-out during high-torque applications. Particularly effective in vibration-resistant applications, the cup point creates permanent seating that maintains positional accuracy in rotating assemblies and sliding mechanisms, making it ideal for heavy-duty fasteners in manufacturing and equipment maintenance.
Specification Summary & Compliance
This set screw features 1/2"-13 UNC coarse threads with Class 2A thread fit tolerance for precise engagement. Manufactured to ASME B18.6.2 specifications ensuring dimensional accuracy and performance reliability. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, meeting international standards for industrial fastener applications.
