A hinge for metal cupboard doors or the like, comprising a first hinged piece such as a hinge plate with one or several counterbored holes for fixing screws and a second hinge piece articulated on the first hinge piece such as a hinge frame or hinge plate, which is also provided with several counterbored holes for fixing screws, wherein the holes of the at least one hinge part are configured as oblong holes. The hinge is provided with a fixing screw bushing which can be fitted into the oblong hole, and whose part fitting into the counterbored area of the oblong hole has a cross-section which differs from a circular form, i.e. a quadratic cross-section, preferably a longitudinally extended rectangular, rectangular with added semicircles of an oval cross-section, and whose longitudinal extension is (the same or) greater than the transversal extension of the counterbored area of the oblong hole and whose inner counter matches the shape of the fixing screw.
