I need to install a haydeck in a small barn and have decided to use doubled-up 2×12’s for the rim joists.
Each support upright has been made from 3 2×6’s and I am wondering what is the safest method of attaching the rim joist to the facing 4.5″?
I have thought of lag bolts but even though I have 4.5″ to attach to, I am concerned at the holding power of bolts going into the three 1.5″ edges that present themselves.
Is it as simple as using more lag bolts of smaller diameter?
All suggestions gratefully received.
