Maybe try Helicoils, Keenserts or EZ-lock hardware, or Pem SI hardware for plastics.

When attaching the parts the trick is to load the force on to the thread of the hardware an and not on the plastic.

There are lots of ways to attach metal hardware to plastics, ultrasonic welding, molded in, press in, etc.
