Metal Screws

[rowens86]

I bought a piece of wood screwed to a piece of slate and i was wondering if the screws they used are safe for my aquarium.

The screws have like a gray coating over the heads and the piece was bought from Aquarium World local fish store http/www.aquariumworld.net/

Im not sure if the screws are safe if you can help please do

Thanks
Rich
