Helix constrain?

Is there a way to constrain 2 parts as a screw and nut? and How?

Cam won't mate to the edge or surface of an helical cut. Tangent works, but overconstrains the coaxial nut/screw. Thaught there was a kind of "gear" constrain to have it work.
Thanks JM

Ended to mate the helical cut to a point on the "nut". Works, but not quite what I was looking for.

Scott Baugh has an example of a helix mate on his site at
