Basic repair is like this.
- Drill out to 4.8 - 5mm
- Tap threads to 6 x 1mm
- Use a 6mm screw with plain nut, screw the insert onto the screw, lock the nut gently
- Cover the threaded screw with a strong loctite and screw the insert in with the screw untill it locks, unwind the nut and remove the screw
- You can counter bore the casting so the top hat seats flush if you need to
