Mechanically fastened appended tabs invisibly secure common edge-abutting wallboard panels to common wood or metal framing members. The fastener appendants are spaced apart tabs extending from the back of and exposed beyond the vertical edges of the wallboard panels so as to be conveniently screw fastened. When screw fastened to common wall framing members, the appended tabs secure the wallboard panels slightly off the framing member front surface to permit offset appendant tabs of abutting wallboard panels to slide between the fastened wallboard panels and the framing members and be engaged by the fastened wallboard panels in a tongue and groove relationship.

A wall or partition comprising first and second coplanar edge-abutting wallboard panels, invisibly secured together along a joinder line at a wall framing member by a first series of a plurality of spaced apart fasteners joined to the first wallboard panel at the abutting edge thereof and held to the framing member, a second series of spaced apart fasteners joined to the second wallboard panel along the abutting edge thereof and with parts of the fasteners extending parallel to said panel from the back side thereof, said second series of fasteners being so located as to avoid contact with said first series of fasteners and said extending parts of said second series of fasteners when the wallboard panels are in coplanar edge-abutting relationship, contacting the back side of the first panel and, in conjunction with the framing member, preventing said second panel from moving away from said framing member in a direction having a component at right angles to the plane of the panels, which wallboard fasteners are each of a single piece of sheet metal having a substantially flat plate portion, a tongue portion extending from the plate portion and coplanar therewith, a pair of web portions, one on each side of the tongue portion and each extending at a right angle from said plate portion and an impaling flange portion extending from each web portion in the same direction, essentially parallel to and overlying said plate portion and opposite to the direction in which the tongue extends, so that the plate portion may contact the surface of the wallboard panel while the impaling flange portion is impaling said panel at an edge thereof, with said fasteners including a walled depressed area in the plate and tongue portions with a longitudinal slot in the tongue portion, which depression extends in a direction opposite to that in which the webs extend.
