Abstract
La présente invention concerne un filet de vis dont le filetage comprend une crête (21) s'élevant depuis le fond (23) jusqu'au sommet (26), le sommet étant formé de deux pics (27,28) séparés par une gouttière (29) dont la profondeur est inférieure à la hauteur de la crête du fond jusqu'au sommet. Le filet de vis de la présente invention peut être utilisé dans les vis à bois en particulier et il est spécialement adapté à la fixation des rails de chemin de fer sur les traverses.
