I was told (as well as read online) that I should use 16d nails for deck framing.

However I have been using nails labeled "Grip-Rite 5-lb 16D 3.5-in Hot-Dipped Galvanized Smooth Box Nails" in the last couple days and honestly they are terrible. The nails are so easy to bend when I hammer 2x8 to 4x8 treated lumber.

Am I using the wrong nails?

Those are not the correct nails, period.

A "Box" nail is thinner than a "Common" nail, and unsuitable for framing.

Per chart found here, 0.162" .vs. 0.135" which is 144% more steel in the common nail (review geometry if you don't get that.)

Box nails, being thinner, are easier to bend, as well; but predrilling can help if you are not a skilled framer - however, the fact remains that box nails are not suitable framing nails. You may find pre-drilling the 2x8 for 16d common galvanized nails to be beneficial, depending on your hammer skills.

    ...But the code specs out 0.135" nails for STRUCTURAL MEMBERS (per your link). Why is a box nail unacceptable?

For framing a deck where you cannot see the nails, an product designed for exterior use is desired. A galvanized framing nail will not rust where a standard framing nail will rust and potentially eventually fail.

For areas you CAN see, I prefer screws, as they won't pull out and can be screwed flush.

It may also be worth it to rent a compressor and framing nailer for a day or two rather than do it all manually, as framing nailers don't tend to end up with bent nails unless you hit an obstruction.

    Well someone down-voted this for some reason, but it would be nice to know what they think is wrong with the answer, so I can improve my responses. Commented May 31, 2016 at 12:48
