Ryan,
I can bring that question up to other inspectors but I still do not feel that using an existing bolt qualifies as a modification. I would again have to see it for sure.

Adam,
Hole theory as you pointed, out is a method to help in understanding the physics of semiconductor operation. Electrons do exist and they are the reason electricity works. They flow from the negative terminal to the positive terminal or from an electron source to a more positive terminal. (Remember opposite charges attract.) Think of a vacuum tube, the electrons generated by the filament and cathode material (thermionic emission) are attracted to and flow to the positively charged plate. As Doug pointed out, early pioneers did not know the actual physics and assumed that current flowing in a wire produced a magnetic field that would affect a compass, naturally flowed in one direction from positive terminal to negative terminal. Since there are no positive charge carriers there is no way for current to flow out of the positive terminal. These early electricians then defined a current flow as something they could measure and that is the "conventional current" flow we use everyday. When using an ammeter in a DC circuit connected so that the positive terminal is connected to the more positive source, an up scale meter movement will result. Hence the confusion between electron and conventional current flow.
