Professional Applications & Engineering Value

This 5/8"-11 UNC square head set screw delivers critical holding power in demanding industrial environments where vibration resistance and permanent positioning are paramount. The steel construction with Rockwell B80 hardness provides exceptional shear strength, preventing thread stripping in high-torque applications common in heavy machinery, manufacturing equipment, and power transmission systems. The coarse UNC thread pattern ensures rapid installation and superior resistance to loosening, while the cup tip design creates concentrated contact pressure for secure shaft positioning in pulleys, gears, and collars. Engineered to ASME B18.6.2 standards, this 2-inch set screw maintains dimensional consistency across production runs, reducing assembly time and ensuring reliable performance in OEM and MRO applications.

Specification Summary & Compliance

This square head set screw features precision Class 2A thread fit with 5/8"-11 UNC coarse threads and right-hand direction. Manufactured to exact ASME B18.6.2 specifications with inch system measurements, ensuring dimensional accuracy across all critical parameters. The product is fully RoHS 3 (2015/863/EU) Compliant and REACH (EC 1907/2006) Compliant, meeting international environmental standards for industrial fastener applications.
