A reverse taper fastener system including a fastener pin having an elongate bearing section adapted to extend through holes in the work pieces where the bearing section tapers inwardly from the leading end toward the trailing end of the bearing section, having an enlarged head integral with the trailing end of the bearing section, and a pintail section at the leading end of the fastener pin which may carry an expansion collet for expanding the holes from a diameter smaller than the bearing section to a diameter larger than same for installing the fastener. The disclosure also comprehends the method of installing the fastener as well as the method of manufacturing the fastener.

A self-dimpling fastener pin for use in forming dimpled fastener joints connecting thin sheets of material including a shank; a head integral with one end of the shank; and, a pintail integral with the opposite end of the shank with the shank, head and pintail coaxial with each other and concentric about the pin central axis. The head defines a tapered head bearing surface on the underside thereof facing the shank and having a size and shape corresponding to the desired size and shape of the dimple in the sheets of material when installation of the fastener pin is complete. The shank defines a shank bearing surface thereon which may be smooth or grooved to support the sheets of material. The pintail is adapted to be gripped to pull the fastener pin into the holes through the sheets of material, pintail first, to install the fastener pin and form the dimple through a dimple bending surface on the shank of the fastener pin. A collar is used if the shank is smooth but may be eliminated if the shank is grooved since the sheets lock the fastener pin in place.

A double action blind rivet assembly comprising an outer sleeve member with an annular head flange at one end and having an initial outside diameter such that it is receivable through the holes in the workpieces and a length such that it projects from the blind side of the workpieces for the formation of a blind head therein; an inner sleeve member with an annular head flange at one end and having an outside diameter larger than the inside diameter of the outer sleeve member so that, when the inner sleeve member is driven into the outer sleeve member from the accessible side of the workpieces, it will expand the outer sleeve member into a prescribed interference fit by expanding the holes through the workpieces with the inner sleeve member also having a length such that it projects from the blind side of the workpieces after it is driven into the outer sleeve member; and internally supporting the inner sleeve member while it is being driven into the outer sleeve member with a blind head former section thereon on the blind side of the workpieces and a gripping section projecting out of the sleeve members on the accessible side of the workpieces so that the gripping section can be used to pull the head former section into the sleeve members after the inner sleeve member is driven to form the blind head on the blind side of the workpieces. The method of using the fastener is also disclosed.
