A couple of days ago there was some discussion here about nailing schedules, nail sizes and nail penetration. As a DIYer I have always followed building code nailing schedules, probably because I had nothing else to go on. However, I never thought much about requirements for nail penetration.
Looking around I found a couple of sources that say nail penetration should be 11X the nail diameter (somewhere around 1 1/2" for 16d) but I couldn't tell if that was penetration into both members being fastened or only into the end piece. Is the 11X a code requirement and can anyone define the term "nail penetration" more clearly? |
