Using deck screws on regular wood stud?
I installed a washer box onto a stud using deck screws. Following this, during a conversation at Lowe's with one of their employees, I was informed that the coating on deck screws is specifically designed for use with pressure-treated wood. According to the employee, using these screws with non-pressure-treated studs could lead to corrosion due to a reaction between the screw coating and the wood.
This information has raised some concerns, and I am seeking clarification. Is the statement regarding the potential for corrosion when using deck screws with non-pressure-treated studs accurate? Should I consider replacing all the deck screws with regular wood screws to avoid any potential issues?

Answer:
Incorrect. Untreated wood contains no copper, so there will be effectively no corrosion of your deck screws. They're probably epoxy coated, and that would be more than sufficient for indoors, even if your plumbing springs a leak.
Modern pressure treated wood contains copper compounds with antimicrobial properties. The copper galvanically corrodes uncoated steel. It also galvanically corrodes zinc, but hot dip galvanized fasteners have sufficient zinc thickness to tolerate the corrosion rate (zinc electroplating is insufficiently thick). This is why special care is warranted in the case of pressure treated wood. Untreated wood just has environmental threats like internal moisture.
