Tips

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
