  • Screwed assembly
    Patent number: 9670946
    Abstract: A screwed assembly consists of at least one pre-punched, upper and an unpunched, lower component, an intermediate layer arranged in between, and a plurality of self-drilling fastening screws which are introduced via a pre-punch hole in the upper component and screwed to the unpunched component 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 when the fastening screws are screwed in, the pre-punches in the upper component are designed as blind holes which are closed by a thin-walled web.
