Subfloor Fasteners for Aluminum
So i have recently pulled up my subfloor, which were super clean, because the floor of the body is aluminum. I did have some corrosion where carbon steel bolts had been added later (Probably by the school district) so it got me thinking, what type of fasteners should I use for attaching plywood subfloor to the aluminium. The original screws were a square drive with a self taping cutter. They look like black carbon steel, but they may have been coated. The whole interior and exterior floor were coated with asphalt coating.
Just trying to secure the subfloor and avoid galvanic corrosion. Any information would be appreciated.
