2X6 “Big V” Tongue and Groove Treated lumber
I got a great deal on a load of 2X6 “Big V” Tongue and Groove Treated lumber to use on my screened porch deck floor. What is the recommended installation procedure for this product? Other than telling me that triple-coated, hot-dipped galvanized, or stainless steel fasteners are recommended, I haven’t got any instructions. Is it installed like regular interior T&G flooring with a nail through the tongue? What nail length? How tight?

Someone has recommended using ACQ approved trim-head finish screws, 2 1/2" or 3". But wasn't clear on how tight I should make them.
