The spacer screw has a first thread section (1) which can be screwed into a base element, a head section (3) which can be introduced into the construction element, a shank section (2) formed between the head section and the first thread section and a recess for the insertion of a tool. A second thread section (4), is additionally formed between the anchoring section and the shank section and has the same core diameter as the anchoring section (6). When using the spacer screw the head section (3) is drawn into the construction element by the second thread section (4) independently of the turning in of the first thread section (1), so that on the one hand the adjustment of the spacing between the base element and the construction element can take place without special measures and, on the other hand, the screw can be used independently of the differences in strength of the base element and the construction element.
