Dingwall Combustion truss rod adjustment

Can anyone tell me the correct Allen key size, please?

9/64" is what you're after 👍

Cheers, Jazzy. Seems a bit bonkers to have mixed metric (bridge and PUs) and imperial sizes (truss rod) for the setup screws. But none of my metric allen keys fit the truss rod so I was scratching my head a bit...
