ABSTRACT:
A clamping device for supporting a workpiece in a clamped condition. The device includes a split head fastener composed of a head having exterior and interior surfaces, and a threaded shaft attached to the head and extending substantially normally from the interior surface. The head is segmented by slots extending from the exterior surface toward the interior surface, and further defines a passageway extending inwardly along the axis from the exterior surface. To clamp a workpiece in the device, a tightening member carried on the shaft is rotated to bring it into contact with the interior surface of the head, in an outer surface region thereof only. This contact forces the segments surrounding the passageway to pivot toward the axis of the passageway, causing clamping of a workpiece received in the passageway.
