I think there are different cams for wheels with different offsets. anyway, the bolts and cams DO NOT go through the holes of the wheel. the design is such that if you loosen the bolt, you can turn the cam so that the curved edge allows clearance for the hub hole and thus the wheel can be lifted on or off.
cams can be flipped to suit your wheel offset as best as possible. I've also use them to go into a wheel stud hole and put the bolt through the wheelstud hole at various times for various reasons, even though that wasn't the original intent AFAIK
