The present invention pertains to a high speed fastening screw (3) comprising a plurality of concavities (321) formed on the threads (32), which are longitudinally connected for being arranged as a state of a single helix. Further, the concavities (S, t) separately located adjacent to the screw head (30) and to the drilling portion (33) are disposed at relative positions for being accurately aligned by an imaginary line (.beta.). In this manner, the configuration of the concavities would efficiently cut and sever the fibers of the object, so as to achieve a lower screwing resistance for a higher screwing efficiency and prevent the injuries to the operators.
La présente invention concerne une vis de fixation à grande vitesse (3) comprenant une pluralité de concavités (321) formées sur les filets (32), reliés dans leur axe longitudinal de façon à former une seule hélice. De plus, les concavités (S, t) séparées adjacentes à la tête de vis (30) et à l'élément de taraudage (33) sont disposées selon des positions relatives faisant en sorte qu'elles soient parfaitement alignées par une ligne imaginaire (.beta.). Ainsi, la configuration des concavités entameraet coupera efficacement les fibres de l'objet de façon à diminuer la résistance au vissage, tout en augmentant l'efficacité du filetage et en prévenant les blessures éventuelles aux opérateurs.
