Professional Applications & Engineering Value
This alloy steel set screw delivers exceptional engineering value in industrial applications where vibration resistance and secure positioning are critical. The 1/2"-13 UNC coarse thread configuration provides rapid installation in machinery, automotive components, and manufacturing equipment, while the square head design enables high-torque application without cam-out issues. The Rockwell C45 hardness ensures the screw maintains its structural integrity under heavy loads and repetitive stress, making it ideal for permanent or semi-permanent fastening in power transmission systems, gear assemblies, and precision equipment. The combination of Class 2A thread fit and cup tip creates reliable seating surfaces that prevent component slippage in high-vibration environments.
Specification Summary & Compliance
This set screw features precise 1/2"-13 UNC coarse threads with Class 2A thread fit tolerance for consistent engagement. Manufacturing complies with ASME B18.6.2 dimensional and performance standards, ensuring interchangeability and reliability. The product meets RoHS 3 (2015/863/EU) compliance for restricted substances and REACH (EC 1907/2006) regulations for chemical safety. With dimensions of 3/4" length, 1/2" head width, and 25/64" head height, this fastener delivers standardized performance across industrial applications.
