Fasteners for attaching PT lumber to concrete

For attaching bottom plates to concrete slab or wall studs/furring strips to concrete walls, I use either Tapcon screws, or hammer drive concrete anchors.

I read recently that PT lumber's moisture would quickly corrode away screws and nails that are galvanized or anything not stainless steel.

If this is true, should I be worrying about the Tapcon screws and hammer set anchors being corroded away?

Tapcon brand anchors are rated for use in ACQ.

Buildex TapconŽ Concrete Anchor

Not all powder actuated concrete anchors are rated for ACQ, yours would have to specifically say. Check the label.

It's not moisture, it's the chemicals used to treat the lumber. Use fasteners which say they are for ACQ treated lumber and you'll be fine.

Edit: Looks like X types faster than I do

Ramset with Ramguard are approved for ACQ. They come in a green box, so they are distinguishable from regular ramsets.
