Beschreibung
Zusammenfassung:	The invention relates to a method for setting a screw, which has an external thread in a front region and a drive in a rear region for introducing a torque into the screw, in a drilled hole in a substrate of a mineral material, in which method an internal thread is produced in the drilled hole by means of a threaded drill provided with a cutting thread, and then the screw is introduced into the drilled hole and in so doing the external thread of the screw is screwed into the internal thread, produced by the threaded drill, in the drilled hole. According to the invention, there is provision that the outside diameter of the cutting thread of the threaded drill is smaller than the outside diameter of the external thread of the screw. The invention further relates to packages comprising objects for carrying out such a method. L'invention concerne un procédé de mise en place d'une vis, laquelle présente, dans une zone avant, un filet extérieur et, dans une zone arrière, un entraînement permettant d'imprimer un couple de rotation sur la vis, dans un trou taraudé dans un substrat fait d'un matériau de construction minéral. Selon le procédé, un filet intérieur est produit dans le trou taraudé au moyen d'un taraud pourvu d'un filetage de coupe, puis la vis est introduite dans le trou taraudé et le filet extérieur de la vis est vissé dans le trou taraudé dans le filet intérieur produit par le taraud. Selon l'invention, le diamètre extérieur du filetage de coupe du taraud est inférieur au diamètre extérieur du filet extérieur de la vis. L'invention concerne en outre des fûts contenant des objets servant à la mise en uvre d'un procédé de ce type.
