Lag screw in rim joist

How far should a lag screw penetrate through the rim joist at house?

Thanks!

If you mean a lag screw holding a deck ledger, the tip should come through the inside of the rim joist.

Are you checking thread depths on lag bolts?

Never in my life…

I check the head sizes and normally that will take into consideration of the depth, most of the time.

The ones I saw today came through. But they did not look like they came through far enough.

Thanks!!!

It’s not like a nail that will back out. You have to unscrew it… I could easily be wrong, but I would have never questioned it.

As long as it penetrates, it’s OK in my book.
