Professional Applications & Engineering Value
This 3/8"-16 UNC steel set screw delivers critical engineering solutions for industrial applications where vibration resistance and permanent positioning are paramount. The coarse thread spacing provides superior grip in soft materials and prevents loosening in high-vibration environments like machinery, automotive assemblies, and heavy equipment. The square head design with external drive allows for high-torque installation without cam-out, while the Rockwell B80 hardness ensures the fastener maintains its structural integrity under repeated stress. Manufactured to ASME B18.6.2 standards, this 5-inch set screw offers reliable performance in pulley systems, gear assemblies, and shaft collars where precise component positioning is essential for operational safety and efficiency.
Specification Summary & Compliance
This set screw features 3/8"-16 UNC coarse threads with Class 2A thread fit tolerance for precise engagement. The fastener complies with ASME B18.6.2 manufacturing specifications and meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations. The square head design measures 3/8" in width and 19/64" in height, providing optimal drive engagement for industrial applications requiring high torque installation.
