My YHM qd mount kept coming loose from my suppressor (to clarify, the full size YHM qd "hub" mount connected to my turbo k). I cranked it on tight with the nicer yhm wrench you have to  buy from them, while the turbo k was in a vice locked in with the Vox block, also used anti seize. Even then, it was still coming loose. This time, I put it back in the vice, and cranked it basically as hard as I could, but now im worried I've messed up the threads. After a substantial amount of force, I felt the mount move a tiny bit more than it had previously. Now, I cant remove the mount no matter how hard I try, it's like it has been rocksetted.

Did I mess the "hub" mount's or the YHM QD mount's threads up? I assume I have, so I guess I’ll have to contact YHM? Hopefully this is fixable right?

Update: Bought a torque wrench, got it off, threads look fine.

Why do you want to remove it?
I would say try a longer wrench

I guess because I want to see if I’ve messed up the threads. If I have, I’d want them fixed if possible

Update: went out and bought a torque wrench, was able to get it off, threads look fine thankfully.

Glad there was no damage.

Try Rocksett next time.

A torque wrench is not the tool for removing stuck fasteners.

That said, it should be useful when reinstalling.

Unless he fuckered the TW by maxing it out.

Something does seem odd so let us know how it goes with YHM CS.
