The easiest way is to use the connect relationship. For the face on the screw, use QuickPick to select Cone (Protrusion 1). For the face on the base, use QuickPick to select Edge (Hole 1) from the top of the inner diameter of the hole. I have attached the example with the relationship created.
Hope this helps,
Edit - looks like two of us were working on it at the same time
