- Space-saving headless design allows flush mounting where clearance is limited
Professional Applications & Engineering Value
This black-oxide alloy steel set screw delivers exceptional engineering value in industrial applications where vibration resistance and corrosion protection are critical. The Class 3A thread fit provides tighter tolerances than standard fasteners, ensuring secure positioning of components in machinery, automotive systems, and manufacturing equipment. The combination of Rockwell C45 hardness and coarse UNC threads enables reliable performance in high-stress environments while facilitating quicker assembly. The headless hex drive configuration is particularly valuable in confined spaces where traditional fastener heads would interfere with adjacent components. This set screw maintains its holding power even under continuous vibration, making it ideal for permanent installations in industrial machinery, power transmission systems, and precision equipment.
Specification Summary & Compliance
This set screw features 1/2"-13 UNC coarse threads with Class 3A fit for precision engagement, manufactured to ASME B18.3 specifications (ASTM F912). The fastener maintains dimensional accuracy with right-hand thread direction and flat tip configuration. Compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations ensures environmental safety and regulatory acceptance for industrial applications worldwide.
