[ARC5] Bristol 6 flute set screws for knobs

[Dave Merrill]

Are these available anywhere? McMaster Carr has a vast inventory of set
screws, none of them Bristol 6 flute that I can find. I believe they are 8
X 36 thread.

I tried posting on the R-390 reflector with no responses. I guess we add
them to the 'unobtanium' list.
