ABSTRACT:
Two or more bodies of sheet-like material are secured together with a single rivet-like fastening device which has an expanded head, a shank extending from the expanded head and a chamfer at the junction of the expanded head and the shank having a radius which is larger adjacent the head and which has bosses extending radially therefrom. An aperture is formed in the first body of material which substantially conforms to the radial dimensions of the shank and the shank is inserted into the aperture. A shaped aperture having radial dimensions which cooperate with the shank to define voids adjacent the shank is formed in the second body of material and the shank inserted into the shaped aperture. The shank is then axially compressed to force the first body over the chamfer and deform part of the first body into the voids in the second body, thus locking the first and second bodies together.
