Abstract
a. Organe de fixation destiné à être vissé dans des alésages prévus dans des éléments de construction à faible densité, tels que les éléments en bois, agglomérés de particules de bois, béton léger, etc. b. L'organe comporte un noyau cylindrique 2, un prolongement pour son actionnement 6 et une nervure hélicoïdale 3 entourant le noyau 2 à la manière d'un filet, le noyau dépassant axialement l'extrémité d'entrée de la nervure dans l'alésage et servant de guidage lors de l'insertion dans l'alésage. c. La plus grande profondeur des spires du filet, en comparaison de vis ordinaires, assure une meilleure tenue dans le matériau, et le guidage par les sections terminales du noyau rend inutile des mesures spéciales pour assurer l'assise de l'organe avant le début du vissage.
