A deck ledger is attached to the house rim joist. Which fastening is generally ACCEPTABLE, and which is NOT?
a.Toenails driven at an angle are acceptable
b.Standard drywall screws are acceptable
c.Through-bolts or approved lag screws in a prescribed pattern are acceptable; nails alone are not
d.Any construction adhesive alone is acceptable
Explanation
A deck ledger must be fastened with through-bolts or approved lag screws laid out per the code table, because they resist the tension pulling the deck away from the house; nails, drywall screws, toenails, or adhesive alone cannot safely carry those loads and are prohibited for ledger attachment.
