I'm about to replace carpet and want to fix some squeaky areas at
the same time.

Since I can tear off the carpet to do this, I don't need to use
those special snap off screws for carpet, right?

Can I just use a generic wood screw (countersunk flat head)?
Is 2 inch about right length?

I'll be interested in the answers to this, as I plan to do the same
thing within the next few months. The carpet needs to be replaced, and
that will be the perfect opportunity to fix the many squeaks in the
floor.
