ABSTRACT:
A force fit connecting element (1), particularly a wheel stud, which may be force fit into in a drilled hole (3) through the exertion of an axial force, having a shank (5) and a stop (4) in the shape of a head, a collar or the like, having a diameter larger than shank (5). The shank (5) has on the side facing the stop (4) a force fit section (10), which is oversized with respect to the corresponding drilled hole (3). The shank (5) has on the side facing away from the stop (4) a section (22) with a fastening thread (23). The force fit section (10) has a multiple-threaded, preferably at least triple-threaded, helical profile (11). The helical profile (11), with respect to the cylindrical surface area of the drilled hole (3), has a contact area fraction (33) of at least 30% and is made by cold forming.
