Guys - Brand new here and hoping I can get some solid advice. I've replaced several exterior studs (balloon construction) due to rot and sill plates due to termites/carp ants. I used 6d 2.5 inch exterior screws to hold everything in place. Is this acceptable (I'm in NY) and is there any acceptable limit for wood spliting when toenailing? If not, can you toenail above the split with a longer fastener? Thanks for any responses!
