A fastener receiver has an insertion portion and a base extending generally transversely to the insertion portion. The insertion portion has an interior surface that is threaded and is configured to receive the shaft of the blocking fastener. The base has a first tier that extends generally radially from the insertion portion and has a diameter that corresponds to the diameter of the entry aperture structure such that the base engages the entry aperture structure radially. A fastener receiving component is disposed on the shaft.
