Thread milling would be a good approach except that I doubt that Gene has 18-inches of Z-clearance on his small mill to thread the length of his desired screw plus spindle clearance to mill to the table might be an issue.

DIN | ANSI .. Either grind a tool out of M2 or equivalent or go shopping for inserts on the web surplus sites. They won't be cheap but a bit less hassle. Single point thread mill?? Lathe sound easier than milling it.
