My son-in-law wants to use pocket holes in an exterior application. Went looking for stainless steel pocket hole screws (Kreg Rockler McFeelys) and really didn't find what I was looking for. Has anyone found a coarse thread ss screw designed for pocket hole use (or did I miss them in my search) ? I did find some SS auger point that might work but they are flat heads not washer heads. Any experiences with exterior pocket holes? Thanks
