One part of the threads (12) of the inventive threaded component (2) is provided with a helicoidal groove (22) that emerges at the thread top. The groove (22) is made in all or part of the threads of one or two end zones, namely the zone comprising the first engaged threads (32) and the zone comprising the last engaged threads (36), and said groove can also be optionally made in the threads in the zone comprising the middle threads (34). The groove reduces the stiffness of the threads having a groove in the end zone(s) in relation to the stiffness of the threads in the zone comprising the middle threads. The tubular threaded joint obtained after screwing the threaded component to a twin threaded component is much more resistant to the cyclical axial compression and/or traction and/or even flexion strains.
Une partie des filets (12) de l'élément fileté (2) présente une gorge hélicoïdale (22) débouchant en sommet de filet. La gorge (22) est réalisée dans tout ou partie des filets d'une ou des deux zones d'extrémité, à savoir la zone de premiers filets en prise (32) et la zone des derniers filets en prise (36), et elle est optionnellement réalisée dans les filets de la zone de filets médians (34); elle diminue la raideur des filets avec gorge de la zone ou des zones d'extrémité par rapport à la raideur des filets de la zone de filets médians. Le joint fileté tubulaire obtenu après vissage de l'élément fileté à un élément fileté conjugué est beaucoup plus résistant aux sollicitations cycliques en traction et/ou en compression axiales et/ou encore en flexion.
