Allen wrench for edwards Thayer valve

[Jackjack]

HiHi. Does anyone know the specific size of the Allen wrench for the Edwards Thayer valve stop arm screw?

I tried four that I have, but they are either a little bit too big or too small.

I searched the forum, but I found only Shires specific sizes, and I'm not in the US, so it's hard to buy directly from the Edwards website.

Thanks in advance!

3/32"

Off the top of my head, an imperial 3/32." The techs may know better though

I literally used one an hour ago on my Edwards bass to tighten up the axials and that pin that holds the connection between the the two rotors. All the same size.
