You've got it. If the primary has 115 turns and is run at 115V, the bolt will have 1V across it.If the primary has 11.5 ohms dc resistance, the effective source impedance of the bolt will be the resistance of the bolt plus 11.5 ohms *(1T/115T)^2 or the resistance of the bolt plus about 0.8 milliohm. This ignores any impedance from leakage inductance.
Using a more conductive bolt, the voltage stays the same and the effective resistance of bolt drops.
A plastic bolt will have no electrical effect. Also, the plastic bolts I've seen won't support the weight of a power toroid once the toroid heats up.
Play safe and play longer! Don't be an "OUCH!" casualty.
Unplug it, discharge it and measure it (twice) before you touch it.. . .Oh!. . .Remember: Modifying things voids their warrantee.
