Professional Applications & Engineering Value
This 1/2"-13 UNC steel set screw delivers exceptional performance in demanding industrial applications where vibration resistance and secure positioning are critical. The coarse thread spacing provides superior grip in softer materials and prevents loosening in high-vibration environments like machinery, automotive assemblies, and power transmission systems. The square head with external drive enables high-torque installation without stripping, while the cup tip ensures positive contact without damaging shaft surfaces. Manufactured from steel with Rockwell B80 hardness, this fastener maintains its integrity under repeated adjustments and harsh operating conditions, making it ideal for permanent positioning applications in manufacturing, equipment maintenance, and heavy machinery assembly.
Specification Summary & Compliance
This set screw features 1/2"-13 UNC coarse threads with Class 2A tolerance for consistent fit and performance. The 3" length and square head configuration meet ASME B18.6.2 specifications for dimensional accuracy and mechanical properties. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental responsibility and workplace safety standards. The right-hand thread direction and cup tip design provide reliable performance in standard industrial fastening applications.
