What are these studs called and where can they be purchased?

[Resonator Guy]

Does anyone know what the baffle board, speaker mounting studs from 50's amps are called and who might still sell them. I am referring to the small bolts with ferrules of some sort near the head so they won't spin after they have been pushed through the holes. The heads are usually decorative with no slots for any kind of screwdriver.
Can these still be purchased??

They are still available. Search for "Decorative head screws" One source is Antique electronic Supply.
It's a real pain to search their on line catalog but I found the item on this page ( Screw - Flower, #8-32, Nickel, package of 4 | Antique Electronic Supply )
Cheers,
Tom

Thanks, Tom. I wouldn't have looked for screws, flower headed or not. Those look perfect.
