ABSTRACT:
A driver with an internal stack of fasteners that feed automatically out the open end of its tubular shaft. Fasteners having spaced grooves complementally fit a plurality of inwardly protruding spaced splines in the driver shaft. The splines also engage the shaft of the fastener to position and stabilize the fastener so that it can be started into a hole. A friction catch adjacent the open shaft end engages the head to prevent inadvertent removal of the fastener from the shaft and a coil spring automatically gently urges the stack toward the open end.
