Abstract: front page image
(EN)A self-locking screw with a raised root is provided. The self-locking screw has a head, a distal end, and a shaft extending between the head and the distal end. The shaft includes a thread with a plurality of turns so as to define a root, the raised root extending over the root for at least a subset of the plurality of turns proximal to the head. The raised root is removably attached to the root and detaches from the root when the self-locking screw is screwed into a substrate such that the detached raised root binds between the self-locking screw and the substrate and/or becomes embedded within the substrate.
(FR)L’invention concerne une vis autobloquante à base surélevée. La vis autobloquante comprend une tête, une extrémité distale, et une tige s'étendant entre la tête et l'extrémité distale. La tige comprend un filetage doté d’une pluralité de spires de manière à délimiter une base, la base surélevée s'étendant au-dessus de la base sur au moins un sous-ensemble de la pluralité de spires à proximité de la tête. La base surélevée est fixée amovible à la base et se détache de la base lorsque la vis autobloquante est vissée dans un substrat de sorte que la base surélevée détachée se lie entre la vis autobloquante et le substrat et/ou s'intègre au substrat.
