ABSTRACT:
Wall panels are fastened to walls or to one another with pairs of identical elically-wound fastener rods which engage each other by turning. Spacer tubes are provided to maintain the desired spacing between panels, or between panels and walls, and to align the helically-wound sections of the fasteners before engaging. Guide prongs may also be used to assist in the alignment of the fasteners with each other before engaging.
