1. A made-up tubular goods connection for releasably coupling first and second tubular members, the connection comprising:
a coupling including a first box end with a first internal wedge thread and a second box end with a second internal wedge thread;
a first tubular member including a first proximal pin end, said first proximal pin end terminating in a first proximal pin end face, and a first external wedge thread; and
a second tubular member including a second proximal pin end, said second proximal pin end terminating in a second proximal pin end face, and a second external wedge thread;
wherein each of the first internal wedge thread, the second internal wedge thread, the first external wedge thread, and the second external wedge thread comprise stab flanks and load flanks; and
wherein a first torque is created by contact between (i) the respective stab flanks and load flanks of the first external wedge thread and the first internal wedge thread and (ii) the respective stab flanks and load flanks of the second external wedge thread and the second internal wedge thread, and a second torque is created by contact between the first proximal pin end face of the first tubular member and the second proximal pin end face of the second tubular member.
