Abstract
An aperture fastener piece has an intermediate head and an aperture shaft, including aperture retention arms extending from a side of the intermediate head. A receiver includes an annular wall extending from a base, and a plurality of plate retention surfaces supported by and positioned inwardly of the annular wall. A coupling plate can be engaged and retained by the plurality of plate retention surfaces within the receiver to couple the doghouse fastener piece and the aperture fastener piece together. Each of the receiver and the coupling plate extends from different ones of the intermediate head as part of the aperture fastener piece and the doghouse shaft as part of the doghouse fastener piece. The coupling plate can extend from a second of the opposite side of the intermediate head as part of the aperture fastener piece, and the doghouse shaft as part of the doghouse fastener piece.
