ABSTRACT:
A tool for toggle-screw anchors in which the anchor sleeve has flanged and threaded ends and an intermediate longitudinally slotted section which collapses radially outwardly (to grip the rear side of a wall while the flanged end is engaged with the front side of the wall) upon movement of the threaded end toward the flanged end, the tool herein being characterized in the provision an elongated body of strip material having a narrow end bent to form a handle and having a wide end with an opening therethrough through which the shank of a hex head actuating screw extends for clamping said wide end between the flange of an anchor sleeve screwed onto said actuating screw and a spacer washer (s) of selected thickness between the head of the actuating screw and the wide end of the body. With the flange of the anchor sleeve thus snugly engaged with the wide end of the body, the anchor sleeve is pushed through an opening in a wall until the flange and side face of the elongated body is against the front side of the wall. The handle may be gripped between the forefinger and thumb of one hand to hold the body against the wall and against turning while a wrench engaged with the head of the actuating screw is turned to cause drawing of the threaded end of the anchor sleeve toward the flanged end thus to radially outwardly collapse the intermediate longitudinally slotted section of the anchor sleeve to grip the rear side of the wall while the flanged end is engaged with the front side of the wall.
