Abstract: A press-fit component is proposed, which can be both press-fitted into an existing hole in a sheet metal component and also punched into sheet metal where there is no hole. The press-fit component exhibits a head with a bearing surface and a shaft which emanates from the bearing surface. The shaft has a trilobular cross-section and may be provided with knurling over at least part of its length. The shaft may be provided with a threaded through-hole. As a result of the trilobular form, the shaft and with it the press-fit element is secured against turning, without deformation of the sheet metal from a plane taking place during press-fitting.
