I was recently told to use only certain types of hardware (screws, joist
holders, etc.) with treated lumber. Apparently, only galvanized hardware
should be used.
If regular type (non-galvanized) hardware is used, chemicals in the treated
lumbers will corrode/dissolve the hardware. If this is true, how long
(approximate of course) would the regular
hardware hold up if used with treated lumber??

It will start to rust in an outdoor environment in a few months in some
areas, a few weeks by the shore. In Arizona, it will last a long time.
Treated or untreated, use galvanized for outdoor use.
If used outdoors, use deck screws (galvanized) screws. These will
eventually corrode and leave black stains near the metal. If you want
to avoid the staining and screw erosion, use stainless steel screws.
These cost much more, however.
If used under cover (barns, garage, shed, etc) any kind of screws may
be used without concern. They should outlast the treated lumber.
I just built a deck using Phillips Contractor Grade screws for pressure
treated lumber. They have a dull green coating they call Durafast to
prevent rusting. Screws are guaranteed for the life of the project.
Bought at Lowes.
you use treated lumber in the outdooors.. fence parts, decks, etc. so it
is out in the weather... you gonna need outdoor weather resistant
hardware like glavanized nails for it.... thats the reason you use
galvanized stuff... forget about the chemicals in the wood....
