hi folks, in a follow up to my shed building woes...
i'm building a 10x15 shed outside. 2x4 walls, 16in on center...
ready to start sheathing (osb, was planning on doing 1/2in) do i nail
or screw sheathing in? I have a nail gun, but part of me thinks it
should be screwed in... what kind of screws if so?

I've put up tons (literally) of OSB sheathing on /Habitat for Humanity/
builds, and we use 8d nails. You can check your local building code,
but I tell the volunteers to stretch their thumb an little finger as
far as they can, then put nails that far apart in every stud.

Be sure to use a moisture barrier. Down here, we put Tyvek on the
outside.

Where is this project located? Any special wind or seismic issues?
Are we building a bunker or a shed?

Steve Bell's suggestion is the way to go. Nails are fast & the right
fastener for sheathing

And per EXT's comment....yeah nail diameter and length is the way to
spec nails and I've nagging the CE/SE's & contractors I know to stop
with the penny designation. But I'm wondering if he'd still
complain since I'd spec them in Imperial units

8d nails (full head style) can range from .113" dia to .131" dia.

IMO, .113 is a little on the skinny side for sheathing nails but
this is pretty normal for 8d gun nails

I prefer .128" or .131" diameter

So for sheathing, imo, the best nail with .131" dia by 2.5"
minimum with spacing at about 4" o/c.

I've actually tested the 10d plywood shorts (.148" x ~2.25") are "too
short" and tend to pull out under cyclic testing.

But again this is a shed...not a fire station or school

cheers
