As for hex shaft, I have found that the Vex hex shaft is extremely high quality and precision, you may want to look into that.

That's a technique for sticking carbon fiber tubes together to make longer carbon fiber tubes.

It is the same concept, but there are two reasons to not use a threaded rod. First, the keyways would have a negligibly small chance of lining up with each other. Maybe a problem, maybe not. Second, you would have to make darn sure that threading never came apart, or even loosened a little bit. If it did, you'd have threading in bending, and that is a very bad time.
