Simpson's website. They have some good information on the different
treatments, manufacturers and some corrosion research that they have

I am looking for informed advice
about fasteners in ACZA treated wood. I was aware that the CBC requires
nails to be corrosion resistant in all treated lumber, but I had never
considered the anchor bolts and other fasteners (light gauge connectors
also). I don't see where anchor bolts are exempted from this
requirement. The most recent Simpson catalog recommends that only
stainless steel fasteners be in contact with ACZA lumber. I have done
some web searching and found two manufacturers of ACZA treated lumber - one of
which suggests that Simpson's research was limited and that G90 hot-dipped
steel is fine in ACZA, and the other suggests that even mild steel is ok in
ACZA. I have discovered that my local lumber supplier stocks the ACZA
treated wood for the larger pieces (3x8 for the top of a foundation wall). I
also found a lumber supplier's website that suggested that the IRC exempts ½
or larger bolts from this requirement.
I'm curious about how others are
dealing with this for nails, screws, anchor bolts, plate washers, other
structural steel connectors and light gauge timber connectors.
