Drilling: Clear the damaged threads with a standard drill. If repairing a spark plug thread, no pre-drilling is necessary when using the special spark plug tap. However, for fluteless taps, larger holes are required.

Checking: Ensure that the thread and pitch of the tap and the bolt match.

Tapping: Use the special taps to cut the holding thread into the cleared hole. It is recommended to use a suitable cutting oil during this process.

Installing the Insert: Place the insert on the 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 it is a half turn below the surface. Do not 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 larger sizes and spark plug taps, use long-nose pliers to remove the tang. Due to the narrow and exact tolerances, the new thread is normally stronger than the original.

By adjusting the language and sentence structure, the instructions are now more concise and easier to follow. The key steps are clearly outlined, and the package components are listed for quick reference. The drilling, checking, tapping, and insert installation processes are also explained in a more structured manner, ensuring a better overall reading experience.
