External-Square-Drive Steel Extended-Tip Set Screws
 |
Tighten these screws to locate and hold components without worrying about your sockets slipping. Four large, flat sides give you reliable torque but slightly less than external hex drives. Like a dowel pin, the tip slides into mating holes on shafts, tubing, and other surfaces. Made of alloy steel, they're strong enough to hold components without wearing down. Also known as half dog-point set screws.
Black-Oxide Alloy Steel—These screws have a dark matte finish that offers minimal corrosion resistance, so they're best for dry environments.
