Abstract

Une structure de vis est décrite. Elle comprend une partie de tige, une section supérieure filetée étant en circonférence dune partie supérieure de la tige et comportant des pas de filetage, une section inférieure filetée étant en circonférence dune partie inférieure de la tige pour le raccord avec la section supérieure filetée et ayant un diamètre extérieur plus petit quun diamètre extérieur de cette section, et plusieurs plans tangents biseautés sur la circonférence de la partie inférieure de la tige, la section supérieure filetée formant une première inclinaison de 5 à 15 degrés et une deuxième inclinaison de 20 à 30 degrés, et les deux inclinaisons, à un point de départ dans chacun des pas de filetage, sont opposées aux deux inclinaisons de la section supérieure filetée dans une position à 180 degrés.
