[TheForge] Need help finding a part -- or it's name at least

[Bruce .]

I'm working on plans for lightweight, portable forges, and I have a good
approach to a problem that uses a very common idea -- but I can't find the
hardware I need to implement it, or even the NAME of the hardware, to
facilitate finding it.

You've all seen keyhole slots:

and so forth.

Well, I have an application in which I want to lock one sheet metal device
to another.  I can put a keyhole slot in the one -- but I need the
appropriate stud for the other.

Anyone have a clue where to look for such a thing?

Right now have no better idea than to use a nail head, the nail retained in
some manner in the opposing part.  I'd like to come up with something
better than that!
