Plywood floor - nail or screw?
(OP)
I have a light framed wood office building. The floor is two layers of plywood. I specified #8 nails for fastening plywood to wood floor joists. This is the typical way I saw. The contractor suggests using screws in lieu of nails. I did saw the nails popped out from outside deck for another project. Any suggestion? Thanks.

I prefer gluing and screwing too. May get some squeakers, but not as many as nails over the years.

Probably has more to do with the type and installation quality of the adhesive.

You should see the new screw guns they have for doing floors. It take a strip of collated screws and has a 4 foot extension so the trigger stays at belt height and you just walk along driving screws into the floor. Do a search for PAM floor screw gun.

For Simpson Strong Tie fasteners see page 25 of Simpson Wood Construction Connectors C-2013. Be sure and read the footnotes about wind design, etc.

It works great for drywall screws as well

If you have a copy of Canada's OS86 (Wood design manual), take a look in the fasteners.
Make an excel sheet for the nails and screws and never have to worry about finding spec data on standard fasteners again
