ABSTRACT:
A screw gun has a flat planar work face adapted to be placed flat against the work. An activator extending from the work face advances a screw along a guideway from a magazine to a driving position. A power unit is independently activated to drive the screw into the work. The screws in the magazine and guideway are mounted upon a flexible strip which has a body at the screw. The body has knobs extending on either side which fit within a groove of the guideway. The strip with the screws therein form a "Z" fold within the magazine and are guided from the magazine by a feed section which has one concave side and one convex side.
