ABSTRACT:
A fastener impact driver device includes a fastener engagement member having a plurality of projections disposed about a lower portion that engages a corresponding peripheral portion of a fastener. The device further includes a positioning member having an upper portion that ultimately receives a force thereupon, and a lower portion that engages a cooperating upper portion of the fastener engagement member whereby a force such a hammer strike is imparted upon the upper portion of the positioning member to drive the projections of the fastener engagement member into the head of the fastener without damage of the fastener engagement member, whereupon the positioning member is removed from the fastener engagement member and a hand tool is removably secured to the fastener engagement member to impart rotary motion to the member and the fastener thereby removing the fastener from or urging the fastener into a workpiece.
