A fastening apparatus for fastening a component B to a component A enables an automatic compensation of tolerances in the separation distance between the two components. The apparatus consists of a receiving element 2, which can be fixed on the component A, an adjustment element 4, which can be screwed to the receiving element via a first thread pairing 28, 48 of a first thread direction, and a fastening screw 6, which can be screwed into the receiving element 2 via a second thread pairing 54, 56 of the opposite thread direction and can be connected with the adjustment element 4 via a detachable drag connection 46, 54, in order to also turn the adjustment element 4 when the fastening screw 6 is turned and to thereby move for the purpose of tolerance compensation in abutment with component B. When screwed to the receiving element 2, the adjustment element 4 can be moved to an end position serving as transport and installation position, in which the receiving element 2 and the adjustment element 4 are held together in one of several pre-determined angle positions via a detachable latch connection.
