The nail polish remover seemed to work.
I filled the cavity with a few drops of the remover and let it stand for a bit. I then squeezed the end of a Q-tip into the hole and twirled it. The Q-tip came away with a bit of red coloring on a couple of occasions, and the screw threaded easily almost all the way to the bottom of the hole.
Afterwards, I cleaned the area with 70% alcohol to remove any residue, since the remover has a lot of ingredients besides the acetone. Before re-attaching the ejector rod housing, I wiped the area with some Rem-Oil to prevent rust. I used a tiny dab of blue Loctite on the tip of the screw, because that is the only portion of the threads that will engage the screw hole. I tried to keep the threaded area oil-free prior to applying the Loctite.
The screw itself does not carry much load, but it has such a small area to grab, because the barrel can only be drilled and tapped very shallowly. The screw engaged the threads for approx. 2 1/2 turns before seating.
Thank you for your help, and we'll see how it functions in the long haul.
