The tool kits listed are the "Internal size". Metric Example: If your bolt is M6x1.0 and your stripped thread is M6x1.0 you will need a M6x1.0 thread repair kit. Inch Example: If your bolt is 3/8-16 and your stripped thread is 3/8-16 you will need a 3/8-16 thread repair kit. The video example shows the speed in which TIME-SERT inserts can be installed in a blind hole applications using a pneumatic push pull tapper. To our knowledge there is no insert on the market that can be installed faster in a hand volume application where a specific depth is required. The insert in the video is a M10x1.5x14mm. Yes Spark plug repair can be done without removing the head by placing a heavy grease on the step tap flutes to catch the chips. TIP: mechanics have mentioned that using a shop vac with a plastic tube taped to the nozzle end works well for removing any stray chips left over.

Once the insert is seated, reverse rotation of the tap handle to remove the installation tool driver from the installed Time-Sert.and mark the tool at the point it can't enter any further. Use a ink marker or even use a small strip 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.

This simplifies installation and produces a strong, permanent repair by allowing the full torque of the fastener to be applied to the repaired threads. Tests in the laboratory have shown that the Time-Sert repairs are equivalent to the original threads in most cases. 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. Yes, loctite may be used on the external threads of the insert, due to the solid wall design there is no danger of it leaking thru to the internal threads. Time-Sert achieves its thin-walled cross-section due to synchronized internal and external threads of the insert.

Insert Driver Oil

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? What is happening is the plating is slightly heaver on some inserts that is why it will feel tighter when screwing inserts on driver tool by hand. You can also bring the bolt to your local fastener house in your area, they will be able to measure it for you. You will need to know the thread size and pitch of the bolt to repair it. The reason for this is simply the weakest link effect. If you only repair the bad hole or holes and leave the others there is a very good chance the other non-repaired holes may fail. S.T.I stands for "Screw Thread Insert" an example would be a TIME-SERT M8x1.25 repair kit would require a M8x1.25 S.T.I tap, this is "larger" than a standard M8x1.25.
