The bolts would have been phosphated from the factory. That finish can vary from lighter gray to black. Multiple places sell kits to darken hardware. I use the black oxide kit from Caswell Plating. You have to protect the finish from rust after you've darkened the color however. There are a lot of uses for the darkening solution in a restoration.
