This 88-piece thread installation and repair kit from AB Tools is designed for professionals and DIYers working with M6, M8, and M10 metric threads in materials like steel, cast iron, and aluminum. Its primary benefit is restoring damaged threads to a condition often stronger than the original, making it ideal for engine repair and automotive applications. A potential consideration is the need for larger pilot holes when using flute-less taps for certain repairs.

For most thread sizes, pre-drilling is necessary. However, the kit includes a special spark plug tap that does not require pre-drilling if you are repairing a spark plug thread.
This kit is suitable for repairing threads in steel, cast iron, and aluminum.
The kit includes inserts for M6 x 1.0, M8 x 1.25, and M10 x 1.5 metric threads. Match the insert size to the original bolt or thread size you are repairing.
The tang is a small protrusion on the end of the wire thread insert that aids in screwing it into the tapped hole. It must be removed after installation to create a flush surface and prevent interference with the bolt.
Yes, this kit is designed as a professional tool and is suitable for commercial or occasional use in automotive workshops and repair centers.
Contact AB Tools or your retailer for information on purchasing individual replacement parts. It is recommended to store all components in the provided tin when not in use.
Yes, flute-less taps typically require larger pilot holes than standard taps with flutes. Ensure you use the correct drill size specified for the flute-less tap.
Ensure the pilot hole is drilled to the correct size and the new thread is tapped cleanly. Check for debris in the hole or on the tap. Use adequate cutting oil.
Ensure the installation tool is correctly aligned with the tang slot before winding the insert. Apply consistent, light downward pressure during installation.
Verify that the correct tap and insert size were used for the bolt. Ensure the insert was fully seated and the tang removed properly. Check for adequate material around the repaired hole.
