Abstract
A hand-held driver tool is disclosed for holding and aligning the axis of elongated fastener with another axis such as the axis of the tool or such as an axis through a pair of apertures in upper and lower belt fastener plates and an aperture in an underlying anvil support means. The preferred driver tool comprises a housing means with an elongated bore within one end of which there is received an expandable chuck means and within the other end of which there is slidably received a driver means. An elongated fastener such as a rivet-nail is inserted within the bore and into the chuck for being driven into a piece such as a belt upon an impact force being applied to the driver. A cone-shaped end on the lower end of the tool is inserted into a cavity in the belt fastener and a cooperating flange abuts the belt fastener to align coaxially the apertures and the axis of the elongated rivet-nail assembly.
