Won't that make the bleed screw expand more than the surrounding
radiator
and make it even tighter?

Doesn't seem to matter - if it expands relative to the housing, being on
a
thread and pressing on a seat, might shift slightly.

Thanks for all your help, I tried them all and failed. so now have a new
radiator on order. None in stock as my wife wanted a round top which are
out of fashion. That such a little thing could be so expensive and time
consuming is unbelievable.

Can you drill it out and tap it?
