Abstract: A wall hanging fastener is provided which is universally applicable in that it can be nailed to the frame of a wall hanging and placed with a serrated edge on a wall nail, or it can be hooked on a wall nail, or in its preferred mode, the wall hanging has a hanging wire which is entrained through special slots in the fastener, and the fastener is slipped over a wall nail. When used according to the preferred embodiment, the fastener will resist axial sliding along the wire, so that once it is centered, if it is centered properly, the painting shall remain in its proper position and will not become angled as do most hanging paintings due to being brushed or the slight jarring of the wall on which the painting is hung.
