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, 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 including a screw drive, 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.
