摘要： 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.
摘要翻译：本发明涉及一种紧固元件，其包括螺母和压力盘，其中螺母具有内部螺纹并且在一端具有止挡表面。提供径向围绕止动表面的搭扣边缘，该搭扣边缘具有径向向内突出的突出边缘。在止动表面，搭扣边缘和突出边缘之间形成腔室。此外，压力盘具有内孔。根据本发明，压力盘具有法兰段和圆筒段，其中法兰段的外径大于圆筒段的外径。此外，凸缘段，圆筒段，搭扣边缘和突出边缘以这样的方式彼此匹配，并且突出边缘突出到螺母的内部中，使得突出边缘和搭扣边缘至少部分地包围凸缘段。
