The fastening table below is based on test data from an ICC-IAS
accredited test lab. Testing was performed using established methods
which are the basis for the deck ledger connection provisions in
R502.2.2.1 of the 2009 IRC and R507.2 of the 2012 IRC.
1. Deck2wall Spacers Model D2W58 shall be installed to ledger with 3 - #8 x 1 5/8” Phillips Square-Driv® or
GuardDog® screws or equal. Use only premium exterior coated or 300 series stainless steel, 1 5/8” minimum
length, #8 or larger. Screws must provide suitable corrosion resistance for the preservative treated lumber and
environmental conditions.
2. Maximum 5/8” nominal wood structural sheathing shall be fastened per code.
3. The tip of the lag screw shall fully extend beyond the inside face of the band joist.
4. Lag screw connections require a washer under the lag screw head.
5. Lag screws and bolts shall be hot dipped galvanized or stainless steel.
6. Lag screws and bolts shall be placed 4 diameters in from the top or bottom of the deck ledgers, and between 2 1/2
and 5 inches from the ends. End fasteners shall be located near the bottom of the ledger. The lag screws or bolts
shall be staggered along the horizontal run of the deck ledger, similar to IRC R507.2.1. See figure below.
* These spacings were limited for consideration of the bending strength of a 2 x 8 minimum ledger between fasteners.
