Abstract:
A tubular threaded connection includes a threaded sub-assembly having a first tubular member, a first torque member threadingly received on the first tubular member, and a second torque member threadingly received on the first tubular member. In forming the threaded sub-assembly, the first torque member is torqued relative to the second torque member. Furthermore, the sub-assembly is configured to receive a second tubular member for torqueing against the sub-assembly.
