<p>A threaded connection including first and second tubular components, each including a respective male and female end, the male end including, on its external peripheral surface, at least one threaded zone and finishing in a terminal surface orientated radially with respect to the axis of the connection, the female end including, on its internal peripheral surface, at least one threaded zone and finishing in a terminal surface orientated radially with respect to the axis of the connection. The male threaded zone includes a first portion in which the width of the teeth, CWTp, increases from a value CWTpmin corresponding to the width of the tooth closest to the terminal surface of the male end to a value CWTpmax corresponding to the width of the tooth furthest from the terminal surface, while the width of the teeth CWTb of the female threaded zone decreases from a value CWTbmax corresponding to the width of the tooth furthest from the terminal surface of the female end to a value CWTbmin corresponding to the width of the tooth closest to the terminal surface, such that the threaded zones cooperate in accordance with self-locking make-up, wherein CWTpmin/CWTbmax≧0.2 and CWTbmin/CWTpmax≰CWTpmin/CWTbmax.</p> |
