ABSTRACT:
An expansion sleeve for attaching objects to a relatively thin panel comprises a hollow headed bolt threaded externally for its full length and threaded internally at an end portion remote from the head. The unthreaded internal portion of the bolt has an inwardly projecting apertured annular shoulder into which a drift pin may be driven to expand the sleeve on the interior side of a panel to which the sleeve is to be attached. A jamb nut pulls the expanded sleeve portion firmly against the inside of the panel member and thereafter a threaded rod is threaded into the interior threads of the sleeve so that a nut on the threaded rod may be tightened against the sleeve head. This draws the inner end of the sleeve toward the panel member to increase the pressure of the expanded sleeve portion against the panel. An object to be attached to the panel is then connected to the protruding end of the threaded rod.
