In Field Repair of Hot-Dip Galvanized Steel

When galvanized steel is delivered to a job site, some common field repairs include: touch up after welding, bending of rebar or pipe, or scratched or flaked coating after rough lifting, banging, or other installation practices. This video provides an overview of field repair practices.

Can you hurt coating by screwing a galvanized screw into a galvanized frame wall,joist,thruss etc at a joint in order to frame the skeleton of a house, my question is screwing a possible future corrosion issue? If yes do I have to paint or spray every screw hole and screw in again? Thank you guys.
