Radiator Plug

Anyone have or know where to buy a 1-1/2" readiator plug, with a hex head (vs the square head you get everywhere)?

I've used flush plugs (or flush seat plugs) that tighten with a special wrench. They are an inverted hex, not the hex design of the originals. They were used on the later radiators like Sun-Rads when the plugs had to be flush with the casting. I find them on ebay.
