Professional Applications & Engineering Value

This 5/16"-18 UNC set screw delivers exceptional engineering value for demanding industrial applications where vibration resistance and permanent positioning are critical. The black-oxide alloy steel construction provides superior corrosion protection while maintaining the Rockwell C45 hardness necessary for high-stress environments. The coarse UNC thread spacing combined with Class 3A thread fit ensures precise engagement and eliminates loosening in machinery, automotive components, and precision equipment. The 90° cone point design creates concentrated pressure points that securely lock components in place, making it ideal for shaft collars, gears, and pulleys where rotational forces are present. The headless design with hex drive allows for flush mounting in confined spaces while providing reliable torque application during installation.
