The flange nut and spring that holds the handwheel on my older (manufactured in 1994) CO2 tank has gotten quite rusty. The place that fills my tank won't fill it again until I replace them. I am finding this much more of a challenge than expected. I found a replacement handwheel with the hardware on ebay but the nut (5/16") turned out to be too large. So, I took the rusty flange nut to the hardware store and used one of those guides with different size bolts to figure out the size of the nut. It seemed to fit the 12/24 bolt. It's a less-common size but I found a nut, took it home, and... it's too small. So, I'm kind of stuck. Does anyone know if there is a standard size on tanks manufactured in the 90's? Or where I can find a replacement? I've been searching online to no avail.
The whole situation is frustrating because the tech who wouldn't fill the tank cited fear of the nut giving way under pressure but, as near as I can tell, the nut simply holds on the handwheel--it doesn't seem to hold any pressure. But I'm up against the wall in the face of his refusal. There is another place in town but they will not fill a tank--they will only exchange them. I am reluctant to take that route because my tank is pretty nice and I hate to lose it. But I may have to take that option if I can't figure out how to replace this nut.
I have attached a pic to make it more clear what I'm talking about.
