Method for aligning and/or readjusting a structural element, in particular a casing or a frame of a window or of a door, with respect to a building body, wherein the alignment and readjustment using a device comprising - a first screw sleeve, - a second screw sleeve, - means for rigidly fastening the first screw sleeve to the structural element, - a screw having a shank and a head, - wherein the first screw sleeve and the second screw sleeve are designed in terms of their threads in such a way that the second screw sleeve can be screwed coaxially into or over the first screw sleeve, - wherein the second screw sleeve has, at one of its ends, means for rotating it relative to the first screw sleeve and a bearing surface as a direct or indirect abutment for the head of the screw, - wherein the second screw sleeve has a through-bore or aperture for guiding through the shank of the screw, - wherein the screw sleeves (3, 9) on the one hand and the screw on the other hand have opposite threads, and - the means for rotating the second screw sleeve relative to the first screw sleeve is an outer polygon, in particular an outer hexagon, after a mounting operation comprising the following method steps: - rigidly fastening the first screw sleeve to the structural element, - coaxially screwing the second screw sleeve onto or into the first screw sleeve, - screwing or hammering the screw with its shank through the bore or aperture in the second screw sleeve into the building body until the head of the screw bears directly or indirectly on the bearing surface and the shank of the screw is anchored in the building body, by rotating the second screw sleeve and thus changing the distance between the building body and the bearing surface of the second screw sleeve, wherein the head of the screw is not corotated when rotating the second screw sleeve. - a first screw sleeve, - a second screw sleeve, - means for rigidly fastening the first screw sleeve to the structural element, - a screw having a shank and a head, - wherein the first screw sleeve and the second screw sleeve are designed in terms of their threads in such a way that the second screw sleeve can be screwed coaxially into or over the first screw sleeve, - wherein the second screw sleeve has, at one of its ends, means for rotating it relative to the first screw sleeve and a bearing surface as a direct or indirect abutment for the head of the screw, - wherein the second screw sleeve has a through-bore or aperture for guiding through the shank of the screw, - wherein the screw sleeves (3, 9) on the one hand and the screw on the other hand have opposite threads, and - the means for rotating the second screw sleeve relative to the first screw sleeve is an outer polygon, in particular an outer hexagon, - rigidly fastening the first screw sleeve to the structural element, - coaxially screwing the second screw sleeve onto or into the first screw sleeve, - screwing or hammering the screw with its shank through the bore or aperture in the second screw sleeve into the building body until the head of the screw bears directly or indirectly on the bearing surface and the shank of the screw is anchored in the building body, by rotating the second screw sleeve and thus changing the distance between the building body and the bearing surface of the second screw sleeve, wherein the head of the screw is not corotated when rotating the second screw sleeve.
