Well, to make the base shape you can draw a side profile and use the Construct > Revolve command.

For doing threads, see this for some links:

But one thing to keep in mind is that screw threads pretty detailed geometry, so you do not really want to model them on things that are not going to be visible, if you were to explicitly model every little tiny feature like every screw thread it will tend to create an extremely heavy model and a very large file size.
