ABSTRACT A device for setting an anchor rod in a bore- hole includes a housing and a socket. The socket is made up of a sleeve and a liner. The sleeve is rotatable relative to the housing and the liner. The liner is in threaded engagement with the anchor rod by a standard thread and with the sleeve by a fine pitch thread. Due to the fine pitch thread engagement of the sleeve and the liner, by rotating the sleeve, which remains axially stationary, the liner and the anchor rod are moved axially with the anchor and also moving axially relative to an expansion sleeve so that the expansion sleeve is expanded into an undercut in the borehole.
