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