Abstract: The self-drilling and slotting fastener with retainer has a thin retainer wire that is used to bring the flat nut portion that is inserted through a wall into position with the hole in the wall for a screw to mate with the threads in the nut. The nut has a rectangular body shape with a thin elongated section extending from away from one side. This elongated section has a drilling point and serrated teeth for making a slot. It looks almost like a car key. The drilling point makes a hole wide enough for the matting screw and is long enough to go completely through the wall. The serrated teeth on the elongated section are used to make horizontal slots on each side of the hole to accommodate the narrow width of the nut body. The resulting slotted hole is clean and provides a smooth and uniform surface on the inner surface of the wall for the nut to rest against. The drilling & sawing section is crimped at the juncture with the body and has a hole in it for being put on the retaining wire.

Abstract: A threadlike retainer cord is used to bring a self-drilling and slotting flat nut inserted through a wall into position with the hole in the surface for a screw to mate with the threads in the nut. The nut has an elongated drilling point with serrated teeth along an elongated side. The drilling point makes a hole wide enough for the matting screw and is long enough to go completely through the wall. The serrated teeth on the elongated section are used to make horizontal slots on each side of the hole to accommodate the full width of the nut. The resulting slotted hole is clean and provides a smooth and uniform surface on the inner surface of the wall for the nut to rest against. This fastening system provides a simple way to fasten objects onto walls without having access to both sides. The retainer cord has elongated ends that are larger than the holes they are put through. The nut is put through the slotted hole in the wall and rotates 90 degrees after dropping through the hole.

Abstract: Objects hung with the improved hook & cord loop hanging system uses one or more adjustable hooks for changing the length of one or more flexible cord loops. This hanging system is an improvement over the hangers described in U.S. Pat. No. 5,947,438. Each improved hanger can either be affixed to the object or to the surface the object is being hung on. The cord loop or loops interface with various supports connecting to or affixed to the object or to the surface when the hanger is on the object. The single hook and single cord configuration provides vertical adjustability by shortening the length of the cord through the turning of the screw the adjustable hook is ridding on. A single hook and double cord configuration provides support and locking for the object. A double hook and double cord configuration provides vertical adjustability and locking capability These hangers can be used alone for small objects or in pairs for larger or heavier objects.

Abstract: Pictures and picture backs are improved with the use of an easel back that is fashioned to be a double hook for hanging the picture on a wall. The double loop hanging system described in U.S. Pat. No. 6,405,466 is improved with the use of this device. The easel flap supports the picture on a surface and allows for the fastening of the picture onto the surface. When it is removed from the picture the easel flap provides a side adjusting means for hanging a picture level on a wall.
