That works, I was just trying to figure out if there was a way to change the mate from the dimension.

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?
