can I use these for attaching ledger board to house (wood siding) for small porch roof project, will it be ok for code or no? I heard code needs 1/2"..? in California Bay Area
Asked by: BigPRO
2018 IRC and DCA-6 dictates the use of 1/2" protective coated or rust resistant lag bolts OR through bolts. There is no alternative listed in these code references. However, the local building official can approve (or deny) the use of structural screws for ledger attachment. There are also specific restrictions as to "where" on the ledger any means of attachment can be placed and used. Keep in mind, if the back side of the band joist is not accessible for inspection the deck must be a free standing deck with no attachment to house.

I'm attaching a Galvanized Skewed left Joist Hanger SUL26Z to an 2"x8"x16' pine pressure treated wood joist. It requires a 16d - 3-1/2" nail. Can I use this screw instead and still be in code compliance?
Asked by: mm
You can use 1-1/2” Strong tie screws if attaching to a single thickness 2” x 8” joist. If attaching to a double rim joist (3” thick) use 2-1/2” screws.

are these as strong as Simpson SD#10 (ie. equivalent to 16d nails or stronger)?

are these as strong as Simpson SD#10 (ie. equivalent to 16d nails or stronger)?
Asked by: handydad
Shear strength for the SDS screw is 250, I believe the average shear strength on a 16D nail is 130. It varies a bit if it's sinker or nail gun nail.
