ABSTRACT:
Systems related to threaded connections whereby off-center axial alignment of connected components is maintained. In one embodiment, threads on one connection component are timed to match the timing of the threads on the other connection component. The one component has a connection sleeve screwed thereon. Once the one component and the other component are mated in the desired axial alignment such that the threads on each joint form a continuous, unbroken thread, the connection sleeve is screwed onto the other component to form the threaded connection.
