On installation: Screw the insert in the hole with loctite to the desired location. Let the insert set up with the loctite before running the insert driver tool through the insert. The loctite will prevent the insert from going to deep into the prepared hole. Counterbore the hole using the tool supplied in the kit. The tool has a built-in depth-stop feature that limits the counterbore to the proper depth for installation of the insert. The tool kits listed are the "Internal size". If you are repairing a M12 bolt or stripped thread you will need a M12 kit. Apply oil to the insert driver to help lubricate it and to minimize the chance of galling the threads of the insert during installation. Why does the installation of a Time-Sert require the use of an STI tap? What is an STI tap? Can a standard tap be used instead?

The insert is provided with a built-in flange that automatically positions its depth during installation. The diameter of the spark plug will be the size. The threads or pitch will be a standard for the diameter. Example if the diameter is M14 the standard pitch will be 1.25 or M14x1.25. If you can provide the spark plug number or make, model, year, liter of vehicle we can give you a part number for the kit and insert required. Use form at the right . No! Because the oversized drain plug has oversized the hole in the drain pan making it larger, so the insert will not hold properly. The 1485 kit will work by reducing the hole from M14x1.5 to M12x1.5 there is no drilling because the tin pans are to thin and the thread would break out entirely. So no oversized drain plugs in tin pan repair.This is common on all inserts, if some of your inserts only screw on a few threads of the driver tool don't worry the driver tool will screw through the insert fine when installing.
