Can anyone advise the size Allen key needed for the Allen head cap screws on the MCDONNELL & MILLER 67 blow down valve body? I have to remove some p[arts to get to it, and i want to make sure i have the right socket before i get into it.
Thanks

Yes, 1/4 Inch Hex. I checked the screws on my boiler and my spare stock.

I've seen both flathead and Allen screws in the field.
