Source for stem bolts

The stem bolts on all of my bikes are rusted. They are all 5 mm wide, 18.5 mm long (shaft length), have the permanent washer and the distinctive stem bolt head shape. I have been unable to find replacement stems bolts anywhere, bike shops, internet bike shops, internet fastener shops. Anyone have an actual source for these distictive bolts?

Do you mean the bolt that clamps the stem cap to the fangled nut? Sounds like all it could be.
These are stainless steel, m6 thread. McMaster-Carr will help
https://www.mcmaster.com
Checked Fastenal? They may have a store near you. You might not get it right on at 18.5mm, it might be 20 instead.

Are the threads all rusted, too? If the bolt is that rare or specific just sand it/naval jelly it.

Yes. I mean the face plate fasteners. I thought they were 5mm wide at the thread, not 6mm, so I thought I needed 5M. Mcmaster.com does not appear to have the tapered head shape w the permanent washer.

The threads are fine. The rust is inside the hex indentation extending out and around the outside surface. I have been unable to remove the inside rust.

Try these guys:

https://www.boltdepot.com/

You may end up having to use a separate bolt and washer to get a suitable replacement, but that's not a problem. Not sure what you mean by "distinctive stem bolt head shape", but most bikes just use plain old hex socket head screws, as found on this page:

https://www.boltdepot.com/metric-socket-products.aspx

These allow you to get the largest size of allen wrench for a given diameter of screw.

Bolt Depot is a great vendor and every time I have ordered from them they shipped next day.

I can almost guarantee any hardware store will have them. I buy lots and lots of bolts for stems for our customers at the hardware shop next to our store, and its a very small one at that.
