 I am looking for ideas on how to couple a stepper motor shaft to a
threaded rod for a CNC setup. The motor shaft is 5mm, and the threaded
rod is #10 (4.8mm). Short of machining an aluminum rod with a setscrew,
is there any off the shelf items for this application? I have scouted
the hardware store shelves but could not come up with anything. I would
appreciate any input on this. Thank you.

Wouldn't a drilled hole for a steel pin be an adequate and simple
solution for a small motor?

Could you take a standard coupling for the #10 rod and drill the
threads out of 1/2 of it at the 5mm size? Set screw, cotter
pin(shear pin), or Locktite the motor shaft end.

A coupler with a female thread and locknut on one end and pin or
setscrew on the other?

        --Use a helical coupling and drill holes for roll pins on both ends.
Minimizes backlash and not too expensive.
