Looking for a panel nut

I am looking for a panel nut that attaches a bracket to a Parker valve. The thickness is 1/8"

If you could please, we’re either going to need the part number of the valve this goes with or for you to provide as close of a thread diameter measurement as you can, preferably with a caliper.

The engineer just said he doesn’t need these anymore, since we are now using Swagelok. Thank you!
