Claim:
An anchor for insertion into a cavity accessible through a hole defined in a hollow substrate to facilitate blind engagement between a first fastener and a second fastener, in order to connect an object to the hollow substrate, comprising: a base plate and a pair of laterally offset arms extending from the base plate, such that each arm includes an engagement structure disposed at a distal end of each arm, wherein the engagement structure of each arm cooperatively supports the anchor and complementarily engages the first fastener, wherein each arm comprises a protrusion formed adjacent the engagement structure, such that a notch is defined between the protrusion and the engagement structure which engages the hole to impede movement of the anchor, the engagement structure including: a collar extending outwardly from each arm for engaging the hollow substrate upon insertion of the anchor into the cavity; and a tang extending inwardly from each arm, generally defining a portion of a first aperture for engaging the first fastener, wherein at least one of the arms includes an indexing element to engage an indexing portion, defined on the second fastener, in order to orient the second fastener during movement from a first operative position to a second operative position.
