-Suitable for steel, cast iron and aluminium.

EASY TO USE:
- Drilling clear the damaged threads with a standard drill (included) (to repair a spark plug thread no predrilling is necessary if using the special spark plug tap). Please pay attention that for flute less taps bigger holes are required.
- Check that the thread and pitch of the tap and the bolt match
- 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 centred 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
- Tang removal. After finishing lift the installation tool and use the tang break tool to remove the tang. For bigger sizes and spark plug taps use long nose pliers to remove the tang. Due to the narrow and exact tolerances the new thread normally is stronger than the original ones.
