Abstract
Abstract A blind hole clamping tool which provides for clamping to an apertured panel having only one side of the panel accessible, by positioning the tool locator disk in the aperture of the panel while utilizing the knurled knob to rotate the eccentrically disposed clamp portion so that it engages the rear side of the panel, whereupon the hand knob at the end of a knurled and threaded rod opposite the eccentric clamp end of the rod is rotated to clamp the parts firmly in position.
