6T or 9T bolt?

[fjbj40]

I have these OEM 12 mm bolts I want to use to mount my hitch. How do you know the difference between a 6 vs 9?

Those are the same bolt.

I believe the number 9 has the straight side and the number 6 is curved. That appears to be a 9T, IMO.

Thank you, and not the rest of the jokers, although it is funny

Most metric bolts are going to have tensile strength ratings as X.X such as 8.8, 10.9 or 12.9 and " 6" or "9" is either an SAE size or a specialty bolt that may be used in high corrosive environments etc.

For a trailer hitch I would be using at minimum a 10.9 rated bolt. Looking at the pictures of your bolts there is a lot of tool marks or other abuse that makes me think those are very soft, low tensile strength bolts.

That is an OEM Toyota bolt
