Not all of the force is transmitted through the bolts (in an ideal world, none of it would be).

Think about the wheels on a car. They are held on with 4-6 studs in single sheer. Some are taking 500+ HP. The bolts/studs only hold the wheel onto the hub and create a HUGE clamping load between the wheel and the hub. All of the power is transmitted through the friction between the wheel and hub.

So, it depends upon what your wheel and spacer materials are. If you use metal, then less sheer force is transmitted to the bolts because you can get enough clamping force to transmit the power. If you use plastic/nylon, you probably can't get enough clamping force, so some power will be transferred as sheer force on the bolts.
