The brass machine screw has a plain finish and a round 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 round head has a domed shape.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.
