Abstract: An adjustable eyebolt key includes a flat stem element having side limiting bars extending along the length thereof, an underside center section of a lesser thickness connecting the side limiting bars and which defines a recess therein and two key rings at opposite ends thereof; a tongue slidably positioned in the recess on the upper surface of the underside center section, with the ends of the tongue having the same thickness as the key ring within which it is slidable so as to adjust the grip of each key ring; a worm rotatably secured on the stem element for engagement with gear teeth at an edge of the tongue for actuating the tongue to move along the stem element so as to adjust the grip of each key ring; and a cross-tie in the vicinity of each key ring which secures the tongue on the stem element so as to permit movement of the tongue along the stem element.
