Zusammenfassung:	The invention relates to a stud (10) for stud welding, having a shank (12), having an axially adjoining flange (14) which projects radially relative to the shank (12) and whose outer circumference is of polygonal design in order to be able to apply a test torque (T) to the stud (10) by means of a tool (40), and having an annular section (16) which axially adjoins the flange (14) and whose front, radially extending annular surface (19) is designed as a welding surface which is to be welded to a workpiece (32), wherein the annular section (16) directly adjoins the flange (14), and the annular section (16) and the flange (14) form a head section (20) which has a uniform outside diameter (D) throughout, and wherein the polygonal shape (22) of the flange (14) extends over the annular section (16) up to its front annular surface (19).
