Beschreibung
Zusammenfassung:	The invention relates to a screwed assembly which consists of at least one pre-punched, upper and an unpunched, lower component (3, 1), an intermediate layer (2) arranged inbetween, and a plurality of self-drilling fastening screws (7) which are introduced via a pre-hole (4) in the upper component (3) and screwed to the unpunched component (1) with the interposition of the intermediate layer. In order to effectively prevent in a simple manner any still uncured intermediate layer material from flowing out of the upper component surface (5) when the fastening screws are screwed in, the pre-holes (4) in the upper component (3) are designed as blind holes which are closed by a thin membrane (6).
