Abstract: A fastener has a screw with an anchor located thereon, the anchor being spaced apart from the head. The anchor has a cut-away portion with a leading edge and a trailing edge of the cut-away portion angling downward. The leading edge angles downward a further distance than the trailing edge. The anchor is spaced apart from the head by a distance corresponding to a thickness of a layer of material to be affixed to a support by an adjustable distance. The layer of material has a small opening therein to accommodate the screw. When the screw is inserted through the opening and into the support, the anchor turns through the opening, even though the opening is smaller than the anchor so that the material is located between the anchor and the head. The screw can then be turned further into the support or further out of the support to adjust the distance between the material and the support in order to align the material as desired.
