ABSTRACT:
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.
