Abstract
Screw fastener jaws for the driver head of an automatic screw feeding and driving apparatus are disclosed for driving screws in face frame drilled holes. A tubular mandrel communicates with a screw feeding passage and a screwdriver passage at a first end to feed screws into the channel and then drive the screws. Spring action moves a plate to close off the free end of the channel to capture the screw. The plate is wide enough to engage the workpiece surface on both sides of the slanted hole. As the mandrel is advanced into the slanted hole, the plate is forced away from the end of the mandrel, releasing the screw for driving into the workpiece.
