I am not quite sure what this is, but it got me thinking, you could get 2 pieces of shaft, tap the ends of both and connect them with a piece of threaded rod. Same concept I think.
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.
