Teraflex Bolts SUCK on the HD carrier

I had to readjust my HD carrier due to the tailgate dipping. Bolts came loose after using BLUE loctite and torquing to specs.

We 3 bolts have rounded enough that a 13mm socket now won't work. I got a 12mm socket to secure it, but now will find replace bolts that are harder and better quality. They rounded out very easily and very disappointed with their quality.

Anyone know the size bolts I would need? Oh, yes used a quality socket.

Oh, don't listen to their techs when they say you don't need to paint under the carrier where the OEM hinge came off. Mine in a few months just started some rust. Glad I got it very early and painted it.

Wont buy anymore TF products from now on. Just poorly made crap that I have seen so far.
