The invention relates to a fastening element, comprising a nut and a pressure disk, wherein the nut has an interior having an internal thread and has a stop surface at an end. A snap-on edge radially surrounding the stop surface is provided, which snap-on edge has a projection edge protruding radially inward. A chamber is formed between the stop surface, the snap-on edge, and the projection edge. Furthermore, the pressure disk has an inner hole. According to the invention, the pressure disk has a flange segment and a cylinder segment, wherein an outside diameter of the flange segment is greater than an outside diameter of the cylinder segment. Furthermore, the flange segment, the cylinder segment, the snap-on edge, and the projection edge are matched to each other in such a way and the projection edge protrudes into the interior of the nut to such an extent that the projection edge and the snap-on edge at least partially encompass the flange segment.

METHOD FOR PRODUCING A CAMSHAFT MODULE AND CORRESPONDING CAMSHAFT MODULE
The invention relates to a method for producing a camshaft module (1), which has a camshaft (2) and a bearing frame (3) with bearing devices (4), wherein the camshaft (2) has a shaft (5) and cams (6) with clearances (7), and wherein the bearing devices (4) have clearances. The invention provides that the shaft (5) is created and/or worked in such a way that the shaft (5) has two different outside diameters, that some of the cams (6) and/or the bearing devices (4) are created and/or worked in such a way that the clearances in the cams (6) and/or the clearances in the bearing devices (4) have different diameters, that the bearing frame (3) is movable along an axis of movement (9) during the production of the camshaft module (1) and is rigid along an insertion direction (10) of the shaft, and that the shaft (5) is inserted in the insertion direction (10) into the bearing frame (3) such that an interference fit is respectively obtained at least between the shaft (5) and at least some of the cams (6).
