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.
