Wp-1850 - Coats & Clark, Inc. ABSTRACT A fastener for use with a hollow wall construction using a conventional toggle bolt and a toggle anchor which is pointed and which has an open groove for receiving the toggle bolt. An end cap within the anchor has an internally threaded head portion and a frangible portion which allows the head portion to separate from the rest of the end cap when the end of the bolt is threaded into the head portion, thus twisting the frangible portion until it breaks. Thereafter the head portion prevents withdrawal of the toggle bolt from the anchor. The end of the groove has a threaded portion adjacent the head 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 to draw the anchor tightly against the interior of the hollow wall.
