Abstract
A wall fastener includes a nut having a major planar structure having a hole for receiving a screw, the major planar structure having a first end with two staggered knife edges on opposite sides of the major planar structure and a second end; and a string, wherein the string is detachably connected to the major planar structure.
Claims16
A nut for a wall fastener comprising:
- a planar structure having a longitudinal direction with a first end and a second end opposite the first end,
- a main hole for receiving a screw extending through a portion of the planar structure between the first end and the second end,
- the planar structure having a knife edge at the first end and a notch at the second end, wherein the planar structure includes two staggered knife edges;
- a minor hole for receiving a string extending through the planar structure at a location adjacent the main hole, and
- a string detachably connected to the planar structure through the minor hole, the minor hole being located such that the weight of the nut causes the main hole to be suspended below the minor hole when the nut is suspended by the string.
