Floorboard screw replacement

[Mvallus]

I have been wanting to replace many of my floorboard screws that are becoming corroded and/or are broken. Anyone happen to know where to find the darker screws? Or has anyone modified their floorboards with a more efficient system? These look like an appealling replacement...http://pyiinc.com/floor-anchors.html

I just used regular stainless replacements and didn't worry about the color. The PYI screws look nice but are pricey!

I think McMaster has them. Black oxide stainless.
