Hamer Diablo truss rod wrench size!

My dudes!

In a VERY rare occurrence, I bumped up my sting gauge significantly and need to adjust the neck a bit.

I realized I don't have a wrench that fits my Diablo. 

Is it a 1/4" or 5/16" socket size? 

Tanks, pals.

It's 5/16, but it's a PITA to get to! The lock nut and string retainer get in the way of most wrenches.  You need the "box wrench" style with a right angle handle.
