A fastener-driving tool comprising a nosepiece, a mechanism for driving a fastener from the nosepiece into a workpiece, and a mechanism for feeding an elongate strip of collated fasteners, such as nails having heads. An elongate track admits the strip and guides it so that a leading fastener is positioned to enter the nosepiece. A pusher is moveable longitudinally along the track over a range of operative positions, between a retracted position and an advanced position, and laterally between the retracted position and an inoperative position. The pusher is biased longitudinally so as to push the strip along the track, toward the advanced position, when the pusher is in the range of operative positions. The pusher is biased laterally toward the inoperative position, in which it can be releasably latched. A button is arranged to be manually depressed to release the pusher.
