Title
(EN) SHEET METAL SCREW
(FR) VIS POUR TÔLE MÉTALLIQUE
Abstract
(EN)
A sheet metal screw which includes a head end, an entry tip end and shank running between the head end and the entry tip end. The shank includes a first portion that runs from proximate the head end and toward the entry tip end and includes a self-tapping thread, and a second portion that runs from the first portion to the entry tip end and forms a self-drilling tip that is unthreaded. The shank includes at least one flute on the self-drilling tip that runs from the entry tip end toward the first portion of the shank.
(FR)
L'invention concerne une vis pour tôle métallique qui comprend une extrémité de tête, une pointe d'entrée et une tige s'étendant entre l'extrémité de tête et l'extrémité de la pointe d'entrée. La tige comprend une première partie qui s'étend à proximité de l'extrémité de tête et vers l'extrémité de pointe d'entrée, et comprend un filetage autotaraudeur, et une seconde partie qui s'étend de la première partie à la pointe d'entrée et forme une pointe autoperceuse qui est non filetée. La tige comprend au moins une cannelure sur la pointe autoperceuse qui s'étend de l'extrémité de la pointe d'entrée vers la première partie de la tige.
