Thougts on repairing plastic threads

You can put a piece of trimmer string in that hole with the screw. Just cut off a small piece from your weed wacker.

I would do the trimmer string fix and add a little JB weld before you put the bolt back in. Let it sit for a day and you should be as good as new.

If you use a JB Weld or epoxy fix (the right way to go, just be sure to spray a release agent (eg WD40) on the screw threads, before insertion. You'll thank yourself when you want to remove the screw.

I'm just curious, would blue lock-tite help at all?

I believe loctite eats plastics. You'd have to check for sure though.

It eats thermoplastics, such as the front bezel on your computer. DAMHIKT.

Your chainsaw case might be fine with LokTite, but there are better fixes out there, anyway. I prefer to fill the hole with amine epoxy (eg. West System), butter the screw with a release agent, and screw it into the hole (product disassembled). After cure, remove screw, and assemble product with your fixed threads. Heat applied to screw head can help release, if your release agent fails.
