A device and method for creating an electrical contact region between an electrical contact shoe and a stud is provided. The stud includes a flange having a contact face facing a threaded shank. A welding portion extending from the flange faces opposite to the contact face. The welding portion is stud welded to a metal sheet workpiece having an approximate thickness of 0.6 mm or less. A cap nut made of a plastic material is fastened to the stud, the plastic material permitting self-locking. To prevent deformation of the metal sheet, a torque ranging from 8 to 10 Nm inclusive is applied to an 6 mm diameter cap nut and a torque ranging from 20 to 23 Nm inclusive is applied to a 8 mm diameter cap nut, the torque selectable to prevent pullout of the contact stud from the workpiece. The cap nut serves a first function of sealing against paint penetration into the electrical contact region and a second function of creating electrical contact between the contact shoe and the stud.
