A fastener and a workpiece assembly comprises a fastener composed of a relatively strong, inflexible material having a shank. Wings are disposed on the shank, and the workpiece has portions thereof composed of a relatively flexible, resilient material. An aperture having a diameter is located through the portions. The wings define an outer diameter substantially greater than the diameter of the aperture. The wings are capable of swaging the apertures, thereby increasing the diameters thereof, to allow for passage of the wings. The relatively flexible, resilient material has sufficient elastic memory so that the diameter of the aperture will become smaller than the outer diameter defined by the wings after being swaged by the passage of the wings. |
