(EN) FAST TAPPING SCREW
(FR) VIS AUTOTARAUDEUSE RAPIDE
Abrégé
(EN)
A fast tapping screw useful for fastening fiber plates on a metallic infrastructure has on the screw core (2) at least one thread (5). The screw core (2) finishes in a conical piercing point (3). On the conical piercing point (3) are symetrically arranged two cutting fins (7) that cut up to a diameter between the diameter of the screw core and the diameter of the outer edge of the thread. When the screw encounters the metallic infrastructure, both cutting fins (7) are broken.
(FR)
Une vis autotaraudeuse rapide utile pour fixer des panneaux de fibres sur des infrastructures métalliques porte sur le noyau (2) de la vis au moins un filetage (5). Le noyau (2) de la vis finit en une pointe conique de percement (3). Sur la pointe conique de percement (3) sont symétriquement agencées deux oreilles tranchantes (7) qui coupent jusqu'à un diamètre compris entre le diamètre du noyau de la vis et le diamètre du bord extérieur du filetage. Lorsque la vis frappe l'infrastructure métallique, les deux oreilles tranchantes (7) se cassent.
