Patent attributes
A screw (10) and a connection produced therewith of a thin metal sheet forming a substructure (40) to a plastics component (30) having a through-bore (32) and having a seal (50) located between the substructure (40) and the component (30). The screw (10) has a shank (13) having a thread-cutting thread (16) and a tip (12) in the form of a boring part, and also a lower thread section (18) having a first thread outside diameter (D18) and an upper thread section (19) having a second, larger thread outside diameter (D19) and having a conically narrowing transition section (22) between the two thread sections (18, 19). The upper thread section (19) has a thread pitch (P2) which is smaller than the thread pitch (P1) of the lower thread section (18). During the production of the connection, the upper thread is screwed into the through-bore (32), wherein a form-fit is produced in the component (30) between the latter and the screw (10) and the material of the component (30) rests in a sealing manner around the upper thread section (19). This produces a combination of a seal without a sealing washer and with a defined distance between the component and the substructure by defined compression of the seal (50).
