sheathing nails
 

I've always used 6d 2" galvanized nails for house sheathing. Some guys I know think the 6d are overkill for 1/2" and 5/8" ply and use 4d 1 1/2". Aren't they a little too small??

I'm just a volunteer with Habitat here in Denver so that's my entire building experience but here's what they use on their houses.

7/16" OSB for the sheathing the walls and 8d common nails.

I'm not a pro builder, just a long-time DIYer, and I've always used twisted galvanized 8d siding nails no matter what the siding.
