A fastener driving tool includes a portable housing defining a fastener drive track. A magazine assembly is carried by the housing for receiving a supply of fasteners and for feeding successive fasteners in a feeding direction into the drive track. A ferrous fastener driving element is mounted within the drive track for movement through repetitive cycles, each of which includes a fastener drive stroke in one direction in which a fastener within the drive track is engaged and moved outwardly of the drive track into a work piece, and a return stroke. A drive piston is operatively connected with the fastener driving element for movement therewith. An actuating mechanism is carried by the housing and is constructed and arranged to initiate movement of the fastener driving element through a fastener drive stroke. A magnet is mounted adjacent the drive track and is operatively associated with the fastener driving element so as to continuously bias the fastener driving element in the feeding direction of the successive fasteners such that during the drive stroke of the fastener driving element, the fastener driving element may engage a leading fastener of the successive fasteners without contacting an adjacent fastener of the supply.
