A welding stud comprising:
- a weldable head and a shank extending from the head;
- wherein the head includes a radial flange of a first diameter and a weldable end of a second diameter less than the first diameter, and the shank includes an external thread and an end region opposite the head, wherein the end region comprises at least two flat angled surfaces which incline towards an axis of the shank in a direction moving away from the head and wherein the end region of the shank includes a first tapered gradation of diameter, and the weldable end includes a weld surface facing away from the end region.
A welding stud comprising a weldable head and a cylindrical shank, and the head includes a radial flange of a first diameter and a weldable end of a second diameter less than the first diameter, and the weldable end projects axially from the flange in a first axial direction and includes a weld surface facing in the first axial direction, and the shank extends from the head in a second axial direction opposite to the first axial direction and includes a helical external thread formed on the shank and an end region opposite the head, and the end region comprises a first flat inclined surface and a second flat inclined surface which are inclined so that the radial distance thereof from the stud axis decreases towards the end of the shank remote from the head, and wherein the end region of the shank further includes a first tapered gradation of diameter.
