Abstract:
A functional element for connection to a sheet metal part, and a method for connecting a functional element to a sheet metal part. The functional element includes a head part, a tubular rivet section extending from the head part and a tubular guide section disposed within the rivet section, with a portion of the guide section extending beyond the open end of the rivet section. When the sheet metal part is pre-holed, the portion of the guide section extending beyond the rivet section serves to dilate the pre-cut hole while centering the rivet section, and the functional element includes security components to provide an enhanced and stable connection as well as to secure against rotation. The guide section can be configured as a self-piercing component for use with a sheet metal part that is not pre-holed.
