If there were one overarching authority on fasteners, it would be the International Code Council. They classify smooth-shank nails as “common” and screw- or ring-shank nails as “deformed,” and specify where they have to be used within an assembly. Deformed nails are only really required in high-wind zones and in some subfloor assemblies.
However, you don’t need to be faced with plywood-ripping winds to understand the value of each type. You can get better building results by simply relying on the best product. Each nail is available in loose or collated versions.
Smooth-shank nails rely on friction between the wood fibers and the shank for holding power, which is sufficient in a lot of conditions, but not all. In applications where wood is routinely expanding and contracting due to moisture, wood fibers lose contact with the shank and significantly reduce the nail’s withdrawal strength.
