Generally, anodized screws are hard to find in specific sizes. If you want them, I'd suggest looking after you know what sizes you need, and just buying them yourself.
Brass screws, same deal.
I was actually thinking about sourcing some anodized screws for myself, so if anyone wants to know where I got them (when I actually buy them), I'll post it here.
Sylvester: What size screws are in the case? (Threads, length, head style, etc?)
