How to attach plywood sheeting to house rim joists.

The rim joist is attached at the ends of the joists to keep the joists stable in the upright position and to carry the weight of the walls and roof above. The rim joist will typically sit on the edge of the sill plate. Your goal is to have the plywood end exactly half way across the joist so that the new plywood can start on this spot.

House floor joists are generally about 8 to 10 inches wide so nail length is not an issue.

A ledger relies on the fasteners and strength of the wood ledger board and rim board of the house to carry the deck live and dead loads. The nail tip must not exceed the width of the floor joist it is being driven into.

Don t stack too much plywood on the same set of joists and overload them. Ring shank fasteners are the recommendation as far as i know but as time has evolved screws have proven to be a better choice of fasteners just don t know if screws have in fact officially made it into the printed documents as yet.
