Composite fasteners (10, 80, or 820) joining panels (24, 26) together are installed by a hand-held tool (32, 128). The fastener is inserted through a hole in the panels, with the head (30) abutting one side of the panels. The tool grips a stem (18, 88, or 880) of the fastener extending beyond the panels, and exerts a pulling force which causes a rotating forming die (44, 153) to advance toward the fastener. The forming die rotates and exerts pressure against the fastener to frictionally heat and deform the shank of the fastener to create an upset head (60, 160). A sensing device (159) stops the movement of the forming die (44, 153) and controls the size of the upset head being formed. The stem (18, 88 or 880) extending from the fastener is fractured by exerting an increased pulling force on the stem. |
