1. A fastening screw comprising:
a screw head; and
an electrically insulating body that has a shaft portion; and
a metal body fastened on an outer circumferential surface of a portion of the shaft portion of the electrically insulating body, and wherein
the metal body has a first axial end, and a second axial end opposite the first axial end, and the first axial end is remote from the screw head, and
the metal body defines a continuous external thread and defines a longitudinal axis, and
the shaft portion of the electrically insulating body emerges from the first axial end of the metal body along the longitudinal axis of the metal body; and wherein
the shaft portion of the electrically insulating body emerging from the first axial end of the metal body has an axial first region extending from the first axial end of the metal body, and wherein an external diameter (d1) of the axial first region corresponds to an internal diameter (di) of the metal body, or the external diameter (d1) of the axial first region is smaller than the internal diameter (di) of the metal body.
