What size deck screw to use
Please help. I have been reading thru this forum to build my deck correctly. I was all set to use #7 or #8 coated trim heads to screw down 5/4 x 6 Brazilian redwood. Then on McFeely's web site, they said "use of trim heads for attaching deck boards is not generally recommended." That only leaves #10 flat head. Why and how come no one on this sites uses #10? Also, should the length be 2 1/2 inches? Thanks for the GREAT advice you all give!
