I ran this past Shigeki Aoshima from Schecter Guitar Research. Here's what he told me:
Truss rod wrench should be 4mm or 5/32” (3.96875mm) could fit (slightly loose but fits almost perfectly). USA models are currently using 9/64” wrench. (We used to build guitar with 1/8”, 5/32” before that)
As for the bridge saddle string action adjustment screws, it is metric and 1.5mm is the one should fit.
