  • Tapping - use the special taps for cutting the holding thread into the cleared hole (recommended to use a suitable cutting oil).
  • Install the insert - place insert on installation tool and position the adjustable ring so that the insert tang is centered in the tang slot. Wind the insert in with a light downward pressure until a half turn below the surface. Don't work against the thread direction as the tang could break.
  • Checking - check that the thread and pitch of the tap and the bolt match.
  • Drilling - clear the damaged threads with a standard drill. (to repair a spark plug thread no pre-drilling is necessary if using the special spark plug tap), please pay attention that for fluteless taps bigger holes are required.
