Of course there is a much bigger problem mounting transformers through the chassis even with a rubber or cork gasket. If said chassis is magnetic, much bigger disruption to magnetic flux than magnetic screws. Replace that section of chassis with non magnetic material or stand transformer on it's own two feet.

Good day

Having made the statment about the long brass screws , would it not be beneficial to mount the OPTXs with brass nuts and isolate them from the chassis and thus useing one point of the OPTX to discharge any static to to the chassis via a wire link, or would this only work if it were a steel chassis.

What are you trying to ground? If it is open frame every lam is isolated, that just leaves two metal frames, or two shells whichever you have, of which both would be seperate from each other.

Ground one secondary for safety and any screens built in, which are sometimes used in signal transformers to fight capacitance, but not the core. Ground any pot by all means but you haven't got one.
