fasteners for 7/16 OSB sheathing on a shed

amakarevic

i sound like a total beginner but was wondering what kind of fasteners to use to hang 7/16 board as sheathing on the 2x4 studs of my shed. 3" framing nails seem much yet trim nails do not seem sturdy enough (i do have a trim nailer). should i go with screws perhaps?

thanks

3 or 4d would be good,

i hope my trim nailer is 4d, going to check ... i am too lazy to be nailing manually

Jackofall1

Nope, trim nailer won't handle the diameter of the nails head.

If you have a framing nailer go ahead and use that, with the minimum size nail that it will take.

Off topic, but I see that you've posted quite a few questions related to this project, so, although it's a relatively small shed, and may not make much difference, it's oftern easier to nail your sheathing on with the walls laying down, than it is to try to hold it in place and nail at the same time. Just make sure that you square the wall up first. Also, it's not a bad idea to wear goggles, particilarly with OSB, as you'll go along with no incident for a while, and then hit a hard spot, and throw a nail back if you're not paying attention.

2" is the smallest it will take, you think that's too long?

Jackofall1

Nope, they will work, and yes much easier that swinging a hammer.

The smallest you can use for the OSB (structural sheathing) is the 2" as mentioned, Item #30 here; http://publicecodes.citation.com/ico...002_par005.htm
Be sure to gap between sheets as stamped on each sheet face.

Nails should go twice as deep into the structure as the osb is deep. This means if you're using 1/2 sheathing then it would need to penetrate 1" into the stud. A 1 1/2" nail is a 6d. I would go with 8d myself which is 2". If you're hand nailing, then use a 8d sinker

gap between sheets? why ?

also, is it better to hang OSB horizontally (8 side down) or vertically (4 side down)?

thanks

The gap leaves room for expansion in the humidity. http://osbguide.tecotested.com/pdfs/en/el812.pdf OSB holds the moisture or water way longer than plywood, not recommended for SPF.http://www.buildingscience.com/docum...d%20in%20walls
If using it as corner bracing and it will be inspected, blocking at all edges is required. Check with your local B.D.

so how much spacing gap should i leave between panels?

also, it is pretty darn difficult to find 2"x.113 nails in the 21 deg collation, which is what my nailer is. but they have 2-3/8. do you think that will be too long for nailing 7/16 to 2x4 studs?

also if smooth shank is OK or should it be ring shank for this application?

thanks
