Abstract

L'invention concerne une vis à bois pour le bâtiment, adaptée pour fixer solidement un matériau en plaque dur, plus dur que des matériaux en bois, sur un lit de bois. Cette vis à bois comprend une partie tige (2) pourvue de filets (21), une partie tête (3) pourvue d'une partie fixation d'outil (31), laquelle partie tête permet de visser la partie tige et présente un diamètre supérieur à celui de la partie tige (2), ainsi qu'une partie collet en trompette (4) dont le diamètre augmente de la partie tige (2) à la partie tête. Dans les filets (21) de la partie tige, l'inclinaison du flanc côté entraînement, côté pointe de la partie tige, est supérieure à l'inclinaison du flanc côté extraction, côté partie tête. Plusieurs nervures en chevron (42), pourvues d'arêtes de type lame (43) s'étendant de la partie tige à la partie tête sur la surface de la partie collet en trompette (4), sont formées sur cette partie collet en trompette (4). Une partie rebord plat (32), reliée en continu à la partie collet en trompette (4), est formée autour de la partie tête (3).
