A screw for fastening metal sections (10) onto a base (11), comprising a shank (2) with a threaded section (5) and an engaging section (3) enabling a screw-in device to be arranged. The section of the shank which is connected to the engaging section (3) is designed as a cone extending in the direction of the engaging section (3). The thread engages into the base (11) whereby the metal section (10) is pressed against the base (11) when it meets the cone section (6). The turning moment can be substantially and appropriately increased by appropriate friction, so that the screw-in operation can be halted depending upon the turning moment.
L'invention concerne une vis servant à fixer des profilés métalliques (10) sur une infrastructure (11), qui comprend une tige (2) comportant une section filetée (5) et une section d'attaque (3) pour placer un appareil de vissage. La section de la tige (2) qui jouxte la section d'attaque (3) est évasée en cône en direction de la section d'attaque (3). La section filetée (5) entre dans l'infrastructure (11), le profilé (10) étant comprimé contre ladite infrastructure (11) lorsqu'il entre en contact avec la section conique (6). Une friction appropriée permet d'augmenter sensiblement le couple, de manière à permettre un arrêt de vissage dépendant du couple.
