Abstract: A ball stud fastener (1) includes a stud stub (2) including a first free end (3), a threaded portion (4), an attachment channel (9), a bead (10), a cylindrical portion (11), a conical portion (12) and a second end (13). The threaded portion (4) is located in the region of the first free end (3). The attachment channel (9) is designed for attachment of a bellow (22) and the like to the stud stub (2), the attachment channel (9) being located between the threaded portion (4) and the conical portion (12) in an axial direction, the attachment channel (9) having a first axial end facing the conical portion (12), the first axial end being located next to the bead (10). The conical portion (12) is arranged between the bead (10) and the second end (13) in an axial direction. The bead (10) is produced by cold forming in an axial direction. The cylindrical portion (11) is located between the bead (10) and the conical portion (12), the cylindrical portion (11) resulting from cold forming of the bead (10).
