The bolts mine came with are not stainless. I did find stainless at the hardware. These were about $2 apiece, so you are in for a large expense.
I had one wheel that only came with the black set. Called up Drew and he had Wheel Pro's ship out an extra set of stainless at no cost. Might want to try that if you haven't already eaten the cost.
