Eights:
Found the link. It's the link to the company's website and it has all of the metric sizes available, as well as an excellent video that shows you the foolproof procedure:
http://www.timesert.com/html/mtrcsert.html
Once you are on that page, also click on the link that says "Click Here for Video Installation" and then select the two videos that are entitled "STANDARD BOLT REPAIR DEMONSTRATION" and “STANDARD BOLT REPAIR CLOSE-UP”.
The key advantage over the heli-coil is that the insert will not back out and they claim it is stronger than the original threads. The bottom three threads are apparently the ones that get "expanded" to lock the insert in place.
