Rust proof screws - where to buy them?

Hi all, im after some rust proof black screws for my side skirts, the 3 small ones that go through the skirt, into the horseshoe clip behind the wing. I would go to toyota but i need some longer ones due to aftermarket skirts! any help would be good, would like them in phillips head to. I got some flat head jappaned ones from b&q, but after leaving them in a tub of water for 2days, they started to rust (test proved my thoughts right:D), so not quite as good as toyotas ones.

thanks! Kevin

Here you go:

have you heard of 'brass' before?

B&Q matey, I've just got mine from there.

If you have rusty ones already and its just surface rust, stick them in a pot of vinegar for a few hours and them brush them with an old toothbrush. The screw them a couple of turns into a strip of metal and spray them or have them powder coated.

Go to a marine/boat store.

A friend who runs a trailer company just got a lot of marine grade steel and seems the biz

I'd use st/st but they wont be black, it would be impossible to powder coat the heads black as youd fill up the cross head drive, just fit st/st then use a small brush to apply some paint to head after youve screwed then into place.
