Abstract

L'invention concerne les vis d'assemblage et, plus spécialement, les vis Parker. La vis 10 de l'invention comprend un élément cylindrique 12 présentant une tête 14 à une extrémité et une mèche de perçage 16 à l'autre. La partie cylindrique 12 porte un filet 18 et la mèche de perçage se distingue par sa section droite, obtenue au moyen de deux cercles se chevauchant partiellement. La vis de l'invention présente une surface de détalonnage appropriée, l'angle de son arête tranchante est inférieur à 90 degrés , et la vis elle-même peut relativement aisément être produite en série.
