ABSTRACT OF THE DISCLOSURE A screw feed apparatus is provided herein for use with a power screwdriving tool. The screw feed apparatus includes an internally threaded adapter detachable by threads to an externally threaded shank portion of said tool with an elongated driver member detachable at one end to a chuck formed with the shank portion and a casing relatively slidably mounted on the adapter. At least one spring is disposed within the casing, for urging the adapter axially outwardly. A pair of brackets is mounted to a forward end of the casing and is provided with guide means for guiding a flexible magazine belt in a direction transverse to a longitudinal axis of the tool, the magazine belt carrying a series of self-drilling screws which are aligned in line and spaced at a regular pitch. A pair of feed sprocket wheels is disposed within the brackets, for feeding the magazine belt intermittently by the regular pitch. A nose piece is mounted to a forward end of at least one of the brackets, for providing a predetermined distance of screw-receiving space between the forward end of the brackets and a workpiece into which the self-drilling screws are driven. A ratchet wheel is supported by one of the brackets so as to co- rotate with the pair of feed sprocket wheels. A slide member is supported on the casing so as to be axially slidable back and forth rectilinearly, the slide member being so arranged as to move toward the ratchet wheel in response to forward movement of the adapter, and to move away from the ratchet wheel in response to rearward movement of the adapter. Finally, a claw means is operatively supported by the slide member so as to force the ratchet wheel to rotate intermittently by the regular pitch as the slide member moves away from the ratchet wheel. This permists a decrease in the size and weight of Abstract Cont. the apparatus as well as greater efficiency in operation by diminishing a forward stroke of a screwdriving tool in each working cycle. The screw teed apparatus is provided with a positionally adjustable nose piece to be pressed against a workpiece and with means for preventing undesirable disengagement of a driver member from a chuck of the screwdriving tool.
