ABSTRACT:
Screwing-in apparatus for set screws which can be operated by a wrench, for the connection of hollow rod elements with junction members of a framework, in which the junction members have threaded bores to receive the set screws and the rod elements have end members with middle bores for the passage of the shanks of the set screws. The heads of the set screws can be applied on inside shoulders of the end members for positioning. Other tubular elements are provided which extend inwardly from an opening in the wall of the rod element and open axially parallel to the middle bore in the end member and against it, in order to guide the drive elements of the screwing-in apparatus. A tubular, curved element forms a guide member for the screwing-in apparatus, in the rod element, in which a drive member or members are rotatable and axially immovable. The end of the tubular element which is turned away from the wrench is configured as a plug holder for the set screw.
