Would OffsetSrf be enough to create the threaded hole for this McNeel screw thread tutorial?

I guess the question is how is the model going to be made physically? Will it be printed or machined?

if so, make them at zero tolerance and run a tap into the threads as a post process. It’ll clean them up easily, and the screws will thread into them perfectly.

Fwiw, I don’t model threads or fasteners anymore-

I grab files from mcmaster carr and use them.
