Abstract

Une vis pour panneau de ciment présente un filetage haut qui commence sur l'extrémité effilée, s'étend sur la tige et se termine au niveau d'un deuxième emplacement axial le long de la tige. Le filetage haut délimite un bord périphérique haut où un flanc avant et un flanc arrière se rencontrent au niveau du bord périphérique haut et délimitent ensemble un angle de filetage haut qui est compris entre environ 30 degrés et environ 55 degrés. Un filetage bas commence sur l'extrémité effilée, s'étend sur la tige et se termine sensiblement au niveau dun premier emplacement axial le long de la tige de telle sorte qu'une longueur axiale du filetage bas est inférieure à celle du filetage haut. Le filetage bas comprend un flanc avant et un flanc arrière qui se rencontrent au niveau d'un bord périphérique bas et délimitent ensemble un angle de filetage bas qui est compris entre environ 50 degrés et environ 70 degrés.
