Modular screw and method of manufacturing a modular screw

A modular screw, wherein the screw has, in an axial direction, the following elements:

• a screw head,
• a shank having
• a first functional portion, for applying a prestressing force, wherein a clamping disk is arranged in the first functional portion adjacent to the screw head, wherein the clamping disk takes the form of a disk spring and is connected and secured to the shank in a positionally fixed manner,
• a second functional portion,
• a third functional portion, wherein a washer is arranged in the third functional portion and is mounted so as to be rotatable about a longitudinal axis of the screw,
• and a fourth functional portion having an external thread,
• wherein the washer is secured in a positionally fixed manner, in the axial direction, between the third functional portion and the external thread of the fourth functional portion by bearing against the second functional portion and the external thread of the fourth functional portion.
