Abstract

A flush joint high torque thread that achieves superior tensile efficiency and compression efficiency. In one example, the thread of a pin member and a box member includes a thread a chamfer with angled shoulders on each side of the thread to minimize radial plastically deformation of the shoulders. The stab flanks each contain a lead-in taper extending no further than a thread pitch line from the thread crest. The load flanks are each perpendicular. The stab flanks engage each other during assembly, but not upon assembly. The load flanks do not engage each other during assembly, and do engage each other upon assembly.
