The present driver for fasteners such as nails, screws and the like is provided with a separator member operatively located between the ejector channel and a fastener supply magazine. The separator member takes up a fastener arresting position in which the separator member reaches between the shafts of two fasteners and a retracted position in which the separator member releases a fastener for movement into the ejector channel. The separator member cooperates with a holding device which holds a fastener in the ejector channel after release by the separator member and prior to the driving stroke. The holding device may comprise two permanent magnets. The separator member has a tip which reaches into the ejector channel to different extents depending on the adjustment of an adjusting device for the separator member.
