An expansion anchor sleeve is adapted for insertion into an expansion anchor hole and has a leading end and a trailing end. An expander member is located at the leading end and can be drawn into the sleeve for expanding the same. An externally threaded bolt has a front portion which extends through the sleeve and engages the expander member to draw the same into the latter, and a rear portion which projects outwardly beyond the trailing end of the sleeve and the expansion anchor hole. A tapped sleeve is threaded onto the rear portion and on its end facing away from the expansion anchor sleeve the tapped sleeve is formed with a head; it also has external threads. An abutment member is threaded into the tapped sleeve and clamps between itself and the head an object through which the tapped sleeve extends. |
