Maybe try 1/4" Whitworth or BSW in your search rather than the TPI
I should be readily available but I'm about to go and have a look on your behalf.
I'll report back

They are not exactly the same but unless you have a precision application and both the nut and studding are precision made you are not likely to notice a difference. If push comes to shove then run a tap through the offending item.
The US one will be 1/4" UNC not UNF and should still be readily available. Do you know the spec of what you actually need? I'm guessing it could be for the veritas clamps in which case it is possibly UNC.
