Their color makes them a very strong substitute for brass. Spax galvanized screws are ideal for most outdoor applications. They re dipped and then spun to distribute the zinc evenly resulting in a surface as smooth as electro-plate but considerably more resistant to corrosion. Stainless screws are recommended for marine applications or wherever you want the best you can get. #6 screws use #1 square drive or phillips bits. #8 and #10 screws use #2 bits. #12 and #14 use #3 bits.
