Fasteners are small course threaded screws, be changed for anything else. This is on a "clam shell" type rifle.
Thanks in advance.

Best way to repair stripped threads in plastic housings?
- Thread starter rathunter
- Start date
I've repaired stripped out wood by "matchsticking", which is shoving some match sticks (with the heads broken off) into the hole, filling with wood glue, sanding flush, then redrilling/tapping the hole. Would probably work the same with some pieces of PLA filament and epoxy?

Any good two-part epoxy should work, like JB Weld. Fill the hole, let it cure, then drill and tap. Another technique I've used on wood, fill hole with epoxy, then just turn the screw in. When it cures, you can then unscrew it, and the threads remain. If it doesn't work, nothing lost. Also, be sure to treat the screw with wax or some release agent before turning it in the epoxy.

i use this for methylene chloride for welding pvc , abs , polycarbonate acrylic, and it is very good, just buy the dispenser and watch how to apply it in youtube.

Q bond , has powdered plastic to fill hole and liquid epoxy to bond it then drill and tap after cured. Powder is black or grey.

If there is enough material around the threads, you can actually buy threaded inserts that are made to go into plastics. I've used a couple different ones. This provides you with metallic threads. Ultimately, they are a pretty strong "fix" for stripped plastic threads, or in my case, no threads at all !
Here is a custom intake manifold top with four inserts (at the studs) to hold a carburetor in place.
See McMaster Carr or Grainger for the various types.
