Bottle Design : Inserting Drafted Helix onto Drafted Spout (Tapered Helix / Threads)

Hi all, am modeling a bottle that has a draft of 2deg applied onto Spout (see attached image). I need to model threads using a tapered Helix, how can I taper Helix ?...OR how can I taper threads?

I agree @S1mon you don't typically need draft there (unless there's some strange conical closure system or something).

There isn’t usually draft on the root surface of the threaded portion of a plastic bottle. That area would be molded with two side pulls.
