Abstract

L'invention est relative à un procédé de fabrication d'une vis à tête spéciale polygonale. Il est caractérisé en ce que la vis est réalisée à partir d'un barreau polygonal dont la section correspond à celle de la tête de la vis, et que le corps de la vis est obtenu par usinage du barreau et comporte à sa naissance sous la tête un épaulement sur lequel est emmanché à force une rondelle pour former l'embase. L'invention s'applique notamment à la fabrication des vis de commande de coffrets électriques ou autres.
