Abstract: An apparatus for securing a component to a panel to provide variable positioning of the component with respect to three mutually perpendicular axes is disclosed, having an elongate threaded stud, a generally planar member with a cylindrical elongate collar projecting therefrom, the collar being threadably engaged with the stud threads and including threads of an opposite direction on an outer surface thereof. The apparatus also comprises an internally threaded fastener for threadedly engaging the external threads of the collar. The internally threaded fastener and the planar member clampingly engage respective opposite sides of the panel upon tightening of the nut and permit variable positioning of the component with respect to the panel along three mutually perpendicular axes without moving the component.
