PURPOSE: A fastener driving tool having wear guard defining fastener guiding surface is provided to achieve improvements enabling a polymeric cover to be effectively employed in a fastener driving tool while preventing excessive wear of the polymeric cover. CONSTITUTION: A fastener driving tool comprises a housing structure having a nosepiece defining a drive track adapted to receive a fastener and to guide the fastener as the fastener is driven from the drive track, a magazine mounted to the housing structure and adapted to store a strip of collated fasteners so that a leading portion of the strip extends from the magazine toward the drive track, a fixed structure fixed to the nosepiece and adapted to confine one of two sides of the leading portion of the strip so as to guide the leading portion of the strip along fastener guiding surfaces of the fixed structure, a hinged structure hinged to the nosepiece, adapted to be hingedly moved between an operative position and inoperative positions, and adapted when disposed in the operative position to confine the other side of the leading portion of the strip so as to guide the leading portion of the strip along fastener guiding surfaces of the hinged structure, the hinged structure including a polymeric cover hinged to the nosepiece and further including a wear guard made of metal and mounted so as to define at least one of the fastener guiding surfaces of the hinged structure.
