In regards to the SS 5/16" bucket spout ( straight one with the flange). I was in the shop this morning and I took a SS 3/8" nut and drilled it out to 11/32" and then let the drill wobble around a bit. I could then take the spout and drive it into the the nut for a good snug fit. I don't know if this will solve the leaking on the ground problem or not. I have 50 of these spouts and will try a few.
