Abstract: The invention is a two-part picture hanging system in which one part is attached to the picture frame and the other part is secured to a vertical wall. The part that is attached to the picture includes a recess designed to inwardly receive a portion of the wall-mounted part of the system. In one embodiment of the invention, the part that is attached to the picture includes a shaped portion that is designed to fit within a complementary-shaped channel in the frame. Once in place, the part can be moved to any desired position along the channel and then locked in place. An embodiment of the wall-secured part of the system is taught in which the part is a standard cap screw having a hexagonally-shaped head. The complementary picture-secured part of the system includes a recess having flat sides and is designed to inwardly receive the cap of the screw with the flat sides of the recess securely contacting two flat sides of the cap.
