Up here in the Northeast, if we are framing a house, we cannot use
screws. Must use nails or you will not pass the framing inspection.

That seems a little strange - what's the rational given, if any?


Nails generally have a greater shear strength than screws, thus the
requirement in some areas are very specific as to the nails used, their
size, makeup, and nailing patterns.


Particularly in earthquake country where shear walls are commonly required
by the building codes. The nailing patterns are very specific.


We have a separate shear wall inspection in the locale where I generally
build, and you are correct, the nailing pattern for that inspection, as
well as full height structural sheathing on single story, and required
overlap of structural sheathing between floors, is very specific.
