1. A modular screw, wherein the screw has, in an axial direction, the following elements:
a screw head,
a shank having
a first functional portion,
a second functional portion,
a third functional portion, for distributing a prestressing force, 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, and
wherein the washer is secured in an approximately positionally fixed manner in the axial direction by bearing against the second functional portion and the fourth functional portion;
wherein the first functional portion is between the screw head and the second functional portion, wherein a clamping disk is arranged in the first functional portion to form a prestressing portion.
