Abstract
A plug assembly comprising a generally cylindrical expansion sleeve having a socket portion which receives a wedging nut. One of the nut and socket portion is tapered such that the sleeve may be radially expanded as the nut enters more deeply into the socket portion. A screw element is threadedly received by the nut and by a clearance opening through the sleeve. The screw element is provided with a head which engages the sleeve on the side axially opposite the socket portion whereby threading of the screw element into the nut draws the latter more deeply into the socket portion. The outer periphery of the sleeve is preshaped to be out-of-round to provide for an interference fit with a cylindrical bore which is to be plugged.
