First, ya just don't "sorta fix the threads"
Second, ya shouldn't of jammed the stud in the case. I can't believe ya just kept forcing it in when ya knew it was F^cked up.
Third, If ya can't screw it in by hand then
stop. It's obvious something is wrong.
Forth The stud only needs to be tighten to only 7 ft lbs and put blue loctite on it 7 ft lb is just a little bit more than hand tight
Fifth, A few Fu^ked up threads on a stud are easy to fix. Ya ever hear of a needle file?
Sixth, WTF ya thought you were going to be able to force on the head nut anyways?
Eighth, You should of stopped before ya started
Ninth, You say it's was your only option
and you knew it would work ? well it didn't
BTW The random nut that just happened to thread on the stud with the F^cked up metric threads Is because the nut had a different thread pitch it might of even been a USA nut. Your an idiot to think it was a fluke
