摘要： A threaded oilfield tubular connection 10 includes a pin member 12 having a first external tapered thread 24 and a second external tapered thread 26. A box member includes a first internal tapered thread 14 and a second internal tapered thread 16. Helical torque shoulders 40, 42 are provided on the pin member and the box member, and an axially spaced between the respective first and second threads. The helix of each torque shoulder includes a plurality of revolutions with compression flanks on both the pin member and the box member.
