Abstract
A device for clamping a pair of workpieces together. The device includes a pair of fastener heads, each defining a segmented head which is designed to clamp a workpiece a passageway in the head, as an interior camming surface in the head is moved axially against a contact surface. The two heads are mounted for axial movement toward and away from contact position at which the camming surfaces of the two heads are simultaneously brought into contact with an associated contact surface, with further movement of the two heads axially toward one another acting to force the segments in each head radially inwardly, substantially the same extent, to produce simultaneous clamping of workpieces held in each head.
