Abstract
The invention provides a rivetless nut plate including a nut, a holding bracket having tubular and bracket portions, and a stem having an enlarged head. The stem is positioned within an aperture of the tubular portion such that the head is resting on a shoulder within the bracket aperture. The tubular portion is positioned within an aperture of a workpiece, such that the bracket portion rests on top of the workpiece. The nut is retained within the bracket portion. Force is applied to a bottom of the workpiece and another opposite force is applied to the stem such that the head expands the tubular portion radially outwardly such that lobes on the tubular portion become embedded into the wall of the workpiece, thereby securing the nut plate to the workpiece. The holding bracket could also be formed of two separate elements, a sleeve having a tubular portion and a bracket.
