The brass machine screw has a plain finish and a flat head with a slotted drive. Brass provides corrosion resistance and offers thermal and electrical conductivity. The material is nonmagnetic. The slotted drive has a linear slot for use with a flat-blade driver. The flat head is cone shaped for use in countersunk holes and has a flat top that fits flush with the mated surface. Machine screws are threaded fasteners that are typically used with nuts or drilled and tapped (threaded) holes. Machine screws are available with a variety of head shapes, which determine how the screw interacts with the mating surface, and drive styles, which determine the type of driver required to install and remove the screw.
