Abstract
A drive rivet fastens a plurality of panel members together as a unit. The drive rivet is installed within preformed holes which are drilled or punched through each of the panel members. The drive rivet includes a head portion which abuts the outer surface of the first panel member when installed. A shank portion extends from the head portion and includes a plurality of expansible prongs on its distal end which protrude out from the opposite end of the panel members. The shank portion includes at least a first area of substantially constant diameter and a second area of decreased diameter less than that of the first area which is not in contact with the panel members when the drive rivet is received therein. A generally elongated bore is formed within the drive rivet which is adapted for receiving an expander pin. The expander pin is driven through the elongated bore which urges the expansible prongs outward, which causes the shanks second area of decreased diameter into engagement with the panel members, in order for securing the panel members in the fastened position.
