Abstract

Vis à os (1) comprenant une tige (3) avec une portion filetée (9), cette tige étant surmontée d'une tête (5) permettant de faire tourner la vis ou de l'enfoncer par impaction. Cette vis à os (1) présente une portion de tige rugueuse (11), située entre la portion filetée et la tête de vis. Pour former cette portion de tige rugueuse (11) on réalise directement dans la matière constitutive de la tige, une alternance de creux (13) et d'aspérités (15), de préférence par mise en forme de la tige (3) à volume de matière constant et, notamment, par moletage croisé.
