Hi Shannon,
It is hard to tell from the photo. I attached a snip of the KB-TZ2 technical guide that shows the identification stamps. There should be notches on the head in addition to the letter marking. The legacy KB-TZ used to have 4 notches. The KB3 also uses capital letters for length identification, so it might be difficult to tell just from the head of the anchor. For additional assistance please feel free to email Hilti's engineering team at hnatechnicalservices@hilti.com.
Regards,
Dani
