high temp threadlocker for plastic?

If you don't mind permanant, how about two part epoxy? Sold in auto parts stores as "JB Weld".

A little loctite holds it fine until I go to 450F or 550F for an hour or 2-- then it pulls loose. The threads on the plastic are stripped.

I've considered just putting the next bigger screw in it's place, but if a little goo can cure it, I'd rather go with the goo than try to locate the perfect, flat headed screw. [the screws are some sort of low profile, washer headed, coarse threaded critters]

Thanks- Jim

There is an RTV based caulking tube of FDA approved high temp glue.

Acts just like what you're used to, and from memory goes above 550F ? If not, bet they have something that does.

Oily, smells like vinegar, dries [cures] within 24 hours and remains rubbery. sounds like it could work to tighten that screw without becoming super permanent.

It cost me $10 to have shipped and am still using it!
