Simpson Strong-Tie DTT2Z DTT ZMAX Galvanized Deck Tension Tie for 2X Lumber with 1-1/2 Inch SDS Screws (20-Pack) - Heavy-Duty Deck Construction & Wood Framing Connector for Outdoor Projects

I was worried that this connector would satisfy the building inspector, but not help the deck post Well was I wrong. the inspector could have cared less. the deck posts were rock solid. These come with all the special screws which drive easily. The only thing to buy is 1/2" bolts and/or rods. You will also need a longer drill bit for some situations. I had some connections where the bolts worked fine. And I had some where longer threaded rods were needed. A 48" long threaded rod from Home Depot was cut as needed for the longer lengths, easy. Glad I had bought extra, they came in handy on a small porch job the next week, not code required but made the work easier and better.
