What nails to use? 2x4 framing, osb sheathing

jw15842

I'm adding a 12x24 addition to my existing garage with 2x4 walls & 2x6's running across for the roof. It's a "slant" roof like a awning.

Need help on what "size" & what "type" of nails to use. Doing it the old fashion way. Hammer & nails, NO nail gun.

Walls:
1. 2x4 pressure treated sub plate
2. 2x4 doug fir top plates
I was thinking 10d or 16d but don't no which one or what type. Don't want to split the 2x4's. I could blunt the nails. Do I use Common, Box, Sinker, Coated, Galvinized? I'm confused.

3. 2x4 trimmer studs nailed to king studs side by side or into headers. Same as above, what size & type?

4. 7/16" 4x8 OSB for wall sheating
Same as above, I was thinking 8d or is that too long? What type and what is the spacing of nails. Is it every 6" around the edges & 12" on the center studs (16" o.c.)?

5. 1/2" 4x8 black/sound board applied next to match up thickness of existing garage. Not sure at all what size or type of nails to use. Is the nail spacing the same as the OSB?

6. 4x8 sheets of hardie/masonite siding applied next. Not sure what the standard thickness of the sheets is yet, probally 1/2" or less. Again what size & type of nails. Is the nail spacing the same as the OSB?

7. Also I might be using some different types of Simpson metal brackets for the 2x6 roof. What size nails & type or screws?

The guys at the lumber box stores didn't have a straight answer on any of this, so I thought I would get some better advice from some experienced people on this board.

Hope this helps.

It depends where you're from. I frame with 8's every day toenailing studs. It's must be a regional thing.

Depends on how you're framing the walls. Are you toenailing or endnailing?

The trimmer gets nailed into both the king stud and toenailed into the bottom of the header.

Apparently so! I've never seen it done, but the code specifically allows three 8's toenailed for each stud. Thanks!

you must be right! But with me, its something thats been past down from generation to generation .We frame with 10's all the time four nails pr stud. we use 8's for sheathing. all tho I have taken down additions that were framed with 8's. Dam! just thinking of all those swings I could of saved over the years.
