ABSTRACT:
A hollow wall fastener using a specially shaped or conventional toggle bolt and a toggle anchor which is pointed and which has an open groove for receiving the toggle bolt. The end of the groove has a threaded portion which cooperates with a threaded portion of an aperture opposite the groove to permit the anchor to pivot with respect to the bolt to a position where the bolt is threadably engaged and locked in the threaded portions of the anchor, forming a "T" configuration behind the surface of the hollow wall. Thereafter the bolt may be rotated, e.g. by turning a screw or fastener body, to draw the anchor tightly against the interior of the hollow wall.
