Abstract: An improved working head for attachment to a conventional poweractivated fastener tool driving base for driving fasteners of the type having a T-head and a bifurcated shank. A pair of spring biased guides align and direct the fastener while it is being driven. An anvil in the path of the fastener controllably deforms the prongs to increase the retention ability of the fastener.
