I would recommend to use the treated torx screws for ACQ (Alkaline Copper Quaternary) treated wood for better corrosion and rust resistance. The treated torx screws like the Redline 2-1/2 Inch Long Torx Trailer Screw for ACQ Treated Wood, part # TFX250ACQ, are plated with a material that will resist the ACQ preservative used in treated wood, which is very corrosive because of the high levels of copper it contains. When using ACQ timber it is necessary to use double-galvanized or stainless steel fasteners.

The plating material used on the treated torx screws is said to be comparable to stainless steel as far as rust resistance, but less expensive.

I am including links to the sizes of the treated torx screws that I have available.
