Professional Applications & Engineering Value

This black-oxide alloy steel set screw delivers critical performance advantages for industrial assembly challenges. The Class 3A UNC coarse threads provide superior engagement in soft materials and rapid installation, while the 90° cone point tip creates permanent witness marks for secure shaft positioning in pulleys, gears, and collars. The hex drive configuration ensures high torque capability without cam-out, making it ideal for machinery, automotive, and manufacturing equipment where vibration resistance and precise component alignment are essential. The headless design solves space constraints in compact assemblies while maintaining full thread engagement throughout the 2" length.
