Truss rod key size on ES models?

Hey everyone,

I can't seem to hunt down my truss rod key. Does anyone know the key size on the ES-335? Are all kits the same size here?

Thanks again and apologies for so many questions!

edit: it seems that a 4 mm key works. Thanks to anyone looking at this!

All the PB kits I have done use the same size key.

4mm seems to be the most popular size, and the kits all seem to use that size, but 5mm is quite common with other guitars and some Fenders have 4.5mm, just to be awkward.
