Abstract
A self-fastening hanger for attaching a picture-frame wire to the rear of a wooden picture frame. The hanger includes a substantially planar body portion, a ring portion which extends outwardly from one end of the body portion, and a pair of prongs which project outwardly in spaced relation from the body portion. The prongs are formed in a spiral configuration, wherein they spiral in opposite directions of rotation, and they each have a plurality of barbs formed thereon which project outwardly from opposite side edges thereof. The prongs are adapted to be embedded into a wooden picture frame for permanently securing the hanger thereto, so that a pair of the hangers can be effectively utilized in combination with a picture-frame wire for supporting a picture frame on a wall.
