Anyways, I guess I edited my message after you replied-
The holes to connect the sprocket and wheel hub are different sizes ((sprocket is larger).
I decided I could still use the right size bolts by selecting the holes on the wheel hub for the smart fastener, but it wont let me select those holes in the smart fastener dialog...How do I make this work?
As for length, if I select a different bolt size, I can get the bolt long enough, but the bolt is too large in diameter for the holes. What do you guys do when adding bolts to the sprocket/wheel assemblies? Am I just doing this a hard way?

I don't really ever use the Smart Fastener option. Instead, I use Machinery's Handbook or other references to manually choose the right size hole for tap/clearance for the specific size hardware that I want.
Then for the CAD models of the hardware, I go over to
McMaster and look through their online catalog for the screw or nut that I want. When you finally get to a page where you can't narrow down the choices of screw options anymore, almost all of the screw/nut pages have a Download link in the left side of the top grey bar, to download a CAD model of that specific hardware in a variety of different 2D and 3D formats, including SolidWorks.
Other times, they may not have the specific CAD model, but they will have a link on the left frame for "Product Specifications" and/or "Technical Drawing". Usually from this information alone, I can recreate the CAD model of that part.
After a while, you'll end up with quite a large library of parts already downloaded, and you'll more or less have everything that you need. I personally put everything I could ever use across multiple projects inside a "Parts Library" folder. For all McMaster-Carr parts I use the naming convention MC-####_PART-DESCRIPTION.SLDPRT where #### is the MC part number (such as 91251A197), and where PART-DESCRIPTION is something like 8-32x0.75-SOCKET-HEAD.
