Abstract: A plurality of screws are held in a screw cartridge that is housed within a magazine, and in a first embodiment a spring urges the screws toward a screw injector chamber where they are driven into a substrate upon activation of a motor-operated screw gun. In the first embodiment, the screw cartridge is a blister pack that is split open by a bar positioned at the leading end of the cartridge. The magazine is positioned normal to a drill guide housing that includes a drill bit housing, a screw injector housing, and a screw discharge housing, and the leading end of the magazine is in open communication with the screw injector housing. The trailing end of the magazine is closed by a snap on end cap, and a spring is positioned between the end cap and a trailing end of the screw cartridge to urge the screws into the screw injector housing. Brackets are used to secure the attachment to the screw gun.
