Metal Connectors for Decks

Figure 1. Install joist hangers tight to the wood. The Joist Clip, a simple spring wire clamp, eases the task and keeps fingers out of harm’s way.

Figure 2. Use the proper nails — at least 3 inches long by .148-inch diameter — for “shear-nailed” joist hangers.

Figure 3. Skewed hangers allow a proper structural connection for 45-degree joists.

Figure 4. Concealed-flange hangers are fastened to the ledger with nails through the folded-in flanges.

Figure 5. Although commonly done, field modifying a joist hanger at the end of the ledger by flattening its flange ruins its integrity.

Figure 6. Concealed-flange hangers can save the day when the joist layout falls next to a ledger bolt.

Figure 7. A variety of post bases are available that both tie down the post and raise it above the footing to keep the end grain dry and rot-free.

Figure 8. Placing the footing after framing the deck is a sure way to align the footing with the main beam. When doing a footing this way, attach the base to the post before embedding it in concrete.

Figure 9. When the footings go in before the deck is framed, bolt-down post bases make precise post alignment a cinch.

Figure 10. Notching a seat in a 6x6 post and bolting the upper part of the post to the girder provides a connection that resists rolling as well as uplift.

Figure 11. On retro­fits, bolting or screwing a 2-by to the back of the post and beam braces the connection.

Figure 12. Retrofit post caps allow existing work to easily be brought up to current requirements.

Figure 13. Hurricane ties make a fast and easy connection that adds significant uplift resistance.

Figure 14. Specifically designed stringer hardware provides a reliable connection to an often under-built attachment. Mount the hardware with structural screws. Nails here would be placed in withdrawal, which is prohibited in the IRC.

Figure 15. Hardware similar to seismic hold-downs provides a reliable newel connection that’s described in a report from the ICC-Evaluation Service.

Figure 16. Narrow-diameter structural screws require no predrilling and can be quickly installed with an impact driver.

Figure 17. One solution to the 2009 IRC’s lateral-attachment requirement is this hold-down-type hardware, applied to joists both on the deck and inside the house.
