||Corrosion tests on zinc coated screws.

My question or concern rather is the protective
properties of zinc on the zinc coated screw used in
residential steel framing. I am interested in any
tests, formal or informal on the screw before and
after it has penetrated two or more pieces of steel.
I am also interested in any information the
Engineering community may have as to the specification
requirements concerning this corrosion problem.
1) the allowable length of time the steel studs
and screws can be exposed to weather conditions.
Especially such conditions found in areas such as
Hawaii, Florida and Asiann climates.
2) once the screw has shown signs of corrosion and
rust, will the process continue afer the walls have
3) What is the Engineering community doing to
address the problem of corrosion, particularly with
the fasteners being that the protective requirements
on screws are much less stringent than on the track
and studs themselves?
