A fastening device includes a receptor portion having an angled through hole extending from a first surface of the receptor portion to a second surface of the receptor portion, wherein the angled through hole has an angled axis. The fastening device further includes a top portion having at least a first flange and a second flange extending generally outwardly from the receptor portion. The flanges generally define a flange plane. The angled axis intersects the flange plane at an intersecting angle between 0 and 90 degrees.
