Assembly for producing a threaded connection for drilling and operating hydrocarbon wells, and resulting threaded connection

An assembly for producing a threaded connection, comprising a first and a second tubular component with an axis of revolution and each respectively provided at one of their ends with first threaded zones and second threaded zones, respectively produced on an outer or inner circumferential surface of the component depending on whether a threaded end is male or female in type, in the form of a first and a second helix each provided with a first and a second taper generatrix, the first threaded zones produced in accordance with the first helix to cooperate together in makeup and the second threaded zones produced in accordance with the second helix to cooperate together in makeup, each of the threaded zones defining a thread profile, viewed in a longitudinal section passing through the axis of revolution, provided with load flanks, stabbing flanks, thread crests, and thread roots, wherein:

• a thread height of threads of the first threaded zones and a thread height of threads of the second threaded zones are each in the range 1 mm to 2.5 mm,
• an angle of the load flanks of the first and second threaded zones with a normal to the axis of revolution is in the range 1 to 20 degrees,
• an angle of the stabbing flanks of the first and second threaded zones with the normal to the axis of revolution is in the range 3 to 25 degrees, and
• a clearance is provided between the stabbing flanks of the first and second threaded zones when the connection is made up.
