Nailing into the 1.5" wide face of a stud

Nailing into the 1.5" wide face of a stud

Nailing into the 1.5" wide face of a stud

(OP)
Does the NDS have any load provisions for using a dowel type fastener (nail, lag screw etc.) into the 1.5" wide face of a typical 2x4 stud? If so, what section is it in?

I do not see any mention of edge distance. We have a situation where we have to put multiple lags into a wall stud. Worried about splits in the future.

RE: Nailing into the 1.5" wide face of a stud

I'd start by looking at Tables 12.5.1C & 12.5.1E, depending on how the stud is loaded.

RE: Nailing into the 1.5" wide face of a stud

(OP)
The studs are vertical and 16" on center. A 2x12 ledger is being placed horizontally against the wall studs. The original construction facenailed (3) 16d common nails through the 2x12 into the 1.5" wide face of the wall stud to attach the ledger. The nails are not strong enough for the total load. Contractor is proposing to add (2) LedgerLok fasteners to the connection. The dead load is currently in the nails since we have not lifted the load off the original.

The concern is splitting the wood since the center distance is not 4d = .92" < .75" provided.

RE: Nailing into the 1.5" wide face of a stud

Most Ledger-Lok screws that I have seen are 3/16" diameter.
Their tag line is that they "replace" 3/8" lag screws... but I have mic'd them at 3/16"
I think an ICC report I have read lists them at .190" (seems close enough).
Commentary says 2.5D for edge distance so... I THINK they are ok.


RE: Nailing into the 1.5" wide face of a stud

ALSO - I realize the dead load is on the nails but I don't know if they will remember that. Seems like relative stiffnesses will dictate where the load goes.
Not saying one can't justify the load sharing that way but I have not heard of doing it (and have always thought that one could not do that).

Maybe it's OK. I'd be interested in seeing where that (load sharing between fasteners of different stiffnesses) is allowed.

Simpson has tables for this
