Yep, those are the ones I used, but i paid more than that for them, about $16 for a dozen. I used the pattern in your second link but I spaced them a little closer. I also used a pair of 16d nails on 16" centers to keep the ledger board tight to the rim joist, just in case it wanted to twist on me.

The nails keep it flat, the headloc bolts keep the ledger from pulling away from the wall. BTW, the headloc fastener was developed because of decks that pulled away from the structure they were attached to, sometimes with fatal results. Nails alone will not keep the ledger attached and sometimes lag bolts don't work as well as people think, especially zinc coated lag bolts.
