Square Head Set Screws
Square head set screws are fully threaded fasteners with a square wrenching head designed for strong holding power and easy adjustment. The square head gives you more surface area for a wrench, helping deliver higher torque and more controlled tightening than many internal-drive styles.
The most common point style is the cup point, which bites into the mating surface to resist loosening under load or vibration. These set screws are widely used to secure rotating or sliding components — such as collars, pulleys, gears, and hubs — onto shafts in industrial and maintenance applications.
American Bolt Corp stocks square head set screws in a range of diameters and lengths, with material options to match strength and corrosion-resistance needs.
