An apparatus for a present depth adapter (10) having a flared body that is narrow at the bottom (68) with a wider top portion (46) and a central recess or throughbore (50) extending therethrough. The present invention (10) comes in a variety of sizes wherein the depth from top to bottom is slightly less than the thickness of common sheetrock (18) used in the industry. The shaft of the screw or nail is inserted through the top of the recess (50) until the head rests thereagainst. The screw or nail is installed and cannot be driven any further once the bottom (68) of the preset depth adapter makes contact with the stud (16) regardless of whether the stud is wood or steel. This results in each screw or nail being countersunk to the proper depth and prevents the hardware from being driven too far into the sheetrock (18) and compromising the fastening integrity thereof. The flared shape of the present invention (10) forms a plug that assures an absolute bond to the sheetrock (18).

I claim: 1. An apparatus and a sheet-shaped material, the apparatus for use with a fastener for attaching the material to a structural member, comprising:a flared-shaped spacer having first and second ends and having a throughbore therein, whereinsaid throughbore is axially disposed to receive the fastener therein so that the fastener can rotate freely therein,a length from the first end to the second end of the spacer is smaller than a thickness of the material,the material including a face paper disposed on a front surface thereof,said first end having a countersunk annular flat surface to receive a head of the fastener thereon, an external surface of the spacer having an annular shape around the countersunk portion at said first end and being outwardly tapered from the second end till the annular shape at the first end, andwhen the fastener passes through the material into the structural member, the second end of the spacer is drawn into the material after the tip of the fastener passes through the material into the structural member until the entire spacer is embedded into the material and the second end of the spacer contacts the structural member so that the first end of the spacer forms a countersunk void on the front surface of the material, andwhen the fastener passes through the material into the structural member, a first portion of the face paper of the material is pulled and tucked into the countersunk void without shearing, and a second portion of the face paper is tucked between the spacer and the material.
