Abstract
An attachment device for joining planar metal members to one another. A tapered passage is formed through the metal members. A tapered metal sleeve is positioned in the tapered passage. An elongated headed fastener is inserted through the sleeve. A bearing washer is positioned between the headed portion of the fastener and the metal members with the bearing washer engaging the tapered sleeve. A spacer washer is positioned between the bearing washer and the metal members to limit movement of the bearing washer against the tapered sleeve. A nut threads onto the threaded end of the fastener. A spacer washer is positioned between the nut and the smaller diameter end of the tapered sleeve to prevent the nut from engaging the smaller diameter and of the tapered sleeve when the nut is threaded on the headed fastener.
