Abstract
The invention relates to a method for emplacing connecting elements in metal sheets or sheet components made of metal by inserting a bolt-like or sleeve-like joining section of the connecting element into a joining opening provided in a metal sheet, so that the connecting element bears with an extended head section against one surface side of the metal sheet and projects with a partial length of the joining section over the other surface side of the metal sheet, and by subsequent pressing of the connecting element in the metal sheet through plastic material deformation by applying a pressing force.
