Home is built in California late 1990s. I recently removed some nails and screwed subfloor on 2nd floor to joint/stud below using yellow zinc plated screws from HomeDepot. Now I realized it has notes this screw is only for non-structural and should not be used on treated lumbers (what woods are considered to be treated?)
Is it a problem to screw yellow zinc plated screw to stud and subfloor? (will it corrode? what does it mean by corrode? will it cause damages to structure over a long time?)
Appreciate your answers!
