You just apply some epoxy inside the female thread, not on the male thread. Then none gets on face of the terminal.
But even if it did you would just wipe off and clean with appropriate solvent before it cures.
"drilling each stud with a vent hole"
Hardware for use inside vacuum systems has such holes, so air isn't trapped to bleed out slowly.
It's bad enough dealing with gasses and H2O trapped in/on the metal without having a cavity that is almost sealed.
"oozes up through the threads"
Maybe the resin, if anything, and filler will be filtered out.
More likely you'll have made a hydraulic press.
Won't be any fun trying to drill a small hole through a stainless setscrew. Unless you have EDM?
Makes $3.42 each look like a bargain (6 mm x 25 mm)
