Steel stud anchor
First Claim
1. A metal steel stud anchor for use with a steel stud comprising a head, a shaft and a pointed tip:
- wherein the shaft is conically shaped and extends from the head to the pointed tip, with the shaft having a top grooved zone adjacent to the head and a threaded portion adjacent to the grooved zone and extending to the pointed tip, said threaded portion having an auger zone proximal to the pointed tip having threads for stretching a hole in the steel stud and pushing debris out of the way as the anchor is inserted through the steel stud and a wedge zone proximal to the auger zone for further enlarging the hole in the steel stud, said wedge zone having threads for forming an increasing rim around the hole in the steel stud formed by the folding of the steel stud material to wedge the anchor in the steel stud and prevent the steel stud from jumping over threads of the threaded portion so it does not strip the steel stud anchor, wherein the shaft diameter has a non-linear progression along the length of the shaft, and wherein the threads extend in a non-linear pitch around the length of the shaft in a linear progression and wherein the head has a central void, wherein the central void extends into the shaft.

Abstract
A metal anchoring fastener fastens millwork onto walls constructed with wall cladding fastened to steel studs. The load typical of a loaded cabinet is borne by the steel stud anchors owing to the mate between the profile of the steel stud anchor and the layers of millwork and wall cladding and steel stud that said anchor penetrates. The pitch of the thread adorning the profile of the steel stud anchor progresses non-linearly along the length of said shaft, the shaft is generally non-linear in profile, and the thread profile is non-uniform along the length of said shaft. The anchor can also support a secondary screw concentrically penetrating the void at the center of the anchor, in order to hang loads from a wall, with or without millwork. Predrilling of the holes can enable installation of these zinc anchors.

24. An anchoring metal fastener comprising:
-
a fastener head equipped with tightening features around a central void a threaded, generally conical shaft with curved sides in cross-section that meet at a tip, a linear progression in thread pitch along the length of the shaft, a thread profile that changes with position along the thread, a non-linear progression of shaft diameter along the length of the shaft, a piercing point at the distal end of the generally conical shaft wherein the threaded shaft has an auger zone proximal to the tip having threads for stretching a hole in the steel stud and for pushing debris out of the way as the fastener is inserted through the steel stud and has a wedge zone proximal to the auger zone for further enlarging a hole in the steel stud and having threads for forming an increasing rim around the hole in the steel stud formed from the steel stud material to wedge the anchor in the steel stud and prevent it from jumping over threads of the threaded shaft so it does not strip the steel stud anchor.

25. A metal steel stud anchor for use with a steel stud comprising a head, a shaft and a pointed tip:
-
wherein the shaft is conically shaped and extends from the head to the pointed tip, with the shaft having a top grooved zone adjacent to the head and a threaded portion adjacent to the grooved zone and extending to the pointed tip, wherein the shaft diameter has a non-linear progression along the length of the shaft, and wherein the threads extend in a non-linear pitch around the length of the shaft in a linear progression and wherein the head has a central void, wherein the central void extends into the shaft and wherein the shaft has a concave curved profile. - View Dependent Claims (26, 27, 28, 29, 30, 31, 32)
