Abstract
Official abstract text for this publication.
A threaded connection includes first and second tubular components each with an axis of revolution. The first component including a male threaded end, the second component including a female threaded end, and both the male and female threaded ends finishing in a terminal surface. The threaded zones include, over a portion defined as in a self-locking make-up, threads, which before the self-locking make-up and when viewed in a longitudinal section passing through the axis of revolution of the first and second components, each include: a thread crest, a thread root, a load flank, and a stabbing flank. A width of the thread crests of each component reducing in a direction of the terminal surface of the component under consideration, while a width of the thread roots increases. A lead of the male stabbing flanks and/or load flanks is different from a lead of the female stabbing flanks and/or load flanks.
