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. 本发明涉及种用于在由矿物结构材料制成的基底中的钻孔中放置螺钉的方法，所述螺钉在前面的区域中具有外螺纹并且在后面的区域中具有用于将转矩导入到所述螺钉中的驱动结构，其中，借助于设有切削螺纹的螺纹钻头在所述钻孔中产生内螺纹，并且接着将所述螺钉引入到所述钻孔中并且此时将所述螺钉的外螺纹旋入到所述钻孔中的由所述螺纹钻头产生的内螺纹中。按照本发明规定，所述螺纹钻头的切削螺纹的外直径小于所述
