Abstract: Semi-automatic, powered nailing is provided preferably by power from a commercially available electric impact torque wrench. The wrench is fitted with a hammer mechanism converting wrench torque to hammer blows. The hammer provides power to a nail feeding mechanism. The nails are in strips in which the nails are in a series one behind another. The feeding mechanism severs the series of nails and/or completes the formation of nails. The nails preferably are formed by hollow tubing cut between nails defining a plurality of points therearound on one side of the plane of nail division and defining a plurality of head forming tabs therearound on the other side of the plane of nail division.
