Une au moins des extrémités de ce taraud comporte au moins une nervure périphérique non hélicoïdale dont l'épaisseur et la hauteur varient afin de lui faire former, au niveau des goujures, des éléments taraudeurs plus ou moins hauts. Application aux tarauds ou aux vis autotaraudeuses destinées à pénétrer des matières d'origine très dures ou résistantes, par exemple des matières plastiques thermodurcissables.
