Strong decks bring beauty and entertaining space to your outdoor living area
Building a safe, strong deck starts with the proper connectors and fasteners
Installing corrosion-resistant connectors and fasteners helps extend the life of your deck
Strong-Drive® SDWH Timber-Hex HDG screw delivers high-strength, wood-to-wood connectivity, such as deck ledger applications
Don’t take chances with guardrail connections. DTT2Z deck tension ties fasten guardrails to deck framing.
Install DTT1Z as a tension tie to meet building codes and eliminate the need to access to the floor joists inside the home
LSCZ adjustable stair-stringer connector offers a concealed connection between the stair stringer and the carrying header or rim board
Provides bearing and uplift resistance
Ideal for preventing lateral movement of joists
The only screw approved with Simpson Strong-Tie connectors
LCEZ end post caps provide a post-to-beam connection in new or retrofit deck applications
Features a 1 in. standoff to resist wood decay
Deck-Drive DWP stainless-steel fasteners are recommended for higher-exposure environments or applications
You answered your own question. If you use a shim of appropriate length it would work.
This is not a #9 screw. The #9 screw permitted for use with some Simpson Strong-Tie connectors is the #9 SD Connector screw shown at the following link: https://www.strongtie.com/strongdrive_exteriorwoodscrews/sd_screw/p/strong-drive-sd-connector-screw. Thank you!
No, the SD #9 replaces 10d common nails (0.148" diameter); the 1/4" SDS screws would be too large. Thank you!
Yes, this can be used for wood to aluminum applications.
Unless you have elephants on the deck, this screw would be way over-kill.
NONE. Get a bracket made for the purpose.
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.
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.
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.
There are different factors that affect the shear strength, i.e. the type of wood it is being installed in, application, steel side plate or wood side plate, the thickness of the side plate, etc. Please visit our website or C-F-2017 Fastening Systems catalog (pages 329-333) for complete information.
