Where Can I Get One Of These From - Off Kitchen Sink - Pic

[pbar]

Can anyone tell me where I might be able to get one of these from, in the pic. It's the centre screw from my Astracast kitchen sink, the head has snapped off, and obviously the drain fitting is loose. The diameter is about 11mm it seems. Even a metal one would do, if it fits, if I can't get white. But so far, even the plumbers that I've tried don't have anything similar.
Thanks!

Looks like the whole fitting has had it.

There's a similar screw included with strainer wastes, available from the diy sheds.

I can't quite tell from the picture, but is the existing waste cracked at the outer edge of the grid?

Thanks very much for your replies.
No, it's just scratched on the drain, it's not cracked.
The only damage is the screw itself.
Ideally I just want to buy another screw the same size, in white, or metal, and I don't mind having to buy a drain 'kit' just to get the screw and I'll save the rest.
Although I wouldn't mind changing the 'grid' bit too if I can get one the same size then it's all nice and new.
The drain 'kits' that I've seen have screws of smaller diameter and the outer diameter of the sunken grid are too big to fit into the recess.
