Abstract
A functional element having a shaft part and a head part has at least one feature providing security against rotation which is provided in the region of a sheet metal contact surface of the functional element. The functional element is characterized in that each feature providing security against rotation comprises a recess provided in the sheet metal contact surface of the functional element with a raised portion disposed at least substantially centrally in the recess or with a raised portion surrounding the recess. With this design the functional element can be straightforwardly be inserted in a thick sheet metal part or in a sheet metal part of higher strength and thus a security against rotation of high quality can be achieved.
