Two metal-to-metal seals of complementary engaging sealing surfaces are provided, one adjacent the end of the pin member, the other axially disposed between the two steps. Reverse angle torque shoulders at the end of the pin member and the interior termination of the box member and hooked threads further characterize the joint and box and pin members.
