threaded post/stud and sheet metal

[battleship81]

Hello-
I'm trying to figure out how to attach threaded post to a flat piece of sheet metal part so that one side of the sheet metal would still be flat, and on the other side, the threads would still be accessible for fasteners to tighten up near to or even coincident to the sheet metal. Think threading a hex bolt fully through a tapped hole in the sheet metal,cutting the head off of the bolt, and the remaining stud would still be sturdy enough to fasten other parts up to the sheet metal.
[ul]let's say something around 11-17 gg. steel
8-32 or 10-24 thread
may need to use different material for threads and sheet metal[/ul]

Would brazing possibly be a solution? I'm not sure if you can use this for different material types.

Many thanks!

So I just found out about pem studs,and I think they may be exactly what I need.

Drawn arc or capacitive discharge weld studs are another option:

Does it need to be completely flat, or is some protrusion allowable? They do make pem studs that are designed to be countersunk, but that's some fairly thin material you're working with. TVP's idea of the CD studs were my initial thought.
