Atomic M1 jam nut size?

[buddhasummer]

As per title. iI someone can tell me the size of the jam nut wrench that would be appreciated, my micrometer appears to be broken. Cheers.

Think I found the answer 11/16?

Scrap that, it's not.

13/16"? I'm just guessing now, I'll exercise patience and just wait for the answer.

Adjustable wrench?

UNF 9/16-18 - Thread between 2nd stage and hose

Threads in diving regulators etc, o-ring sizes

I think he's looking for the wrench size....

Although all of my "jam nuts" are the big heat sinks that have "M1" engraved in them. They take a different wrench than the jam nuts on a B1.

Is this what you have?

Yes, that's the one with the M1 cut out of the nut. Yes, wrench size is what I'm looking for. Yes, I have an adjustable wrench but it's too wide to use, so given I need to buy a tool anyway figured I'd just get the correct size wrench. Thanks.

Description says this is the one for the Heat sink....

Thin Spanner Wrench 11/16"
