Loose screw on horizontal stabilizer need fix

I have a loose screw on the front of the removable horizontal stabilizer on my Predator II.

The threads on the screw appear to be good, but won't tighten up. I really don't want to fill the hole in the pedestal, re-drill and tap.

The screw is holding, you can't pull it out without turning the screw, but you can't tighten it.

Anyone have a simple fix for this? I thought possibly silicone on the threads., so it could still be removed if necessary, but the screw would be seated.

Any help would be appreciated.

remove the screw and put a drop of thin CA glue on the threads. Let it dry then re-thread by inserting the screw a bit, backing out and in a bit more, until it is in all the way.

If you have a metal screw to use for re-tapping that is better.

Wax the screw. Car wax will work. Place a drop of epoxy on the threads near the tip of the screw and install the screw in the hole with the loose threads. Let the epoxy cure and remove the screw. You mat need to trim the epoxy to get the stab to sit flat on the pedistal when cured.
