I'm hoping someone can explain how this is supposed to work. I have come to the conclusion that at least one of the following is true:
1) It won't work
2) I'm overthinking it.
3) I'm missing parts

If I put this through the lever arm on my throttle body and put a nut on it, then torque it enough to prevent the cable from sliding, it would be too tight to pivot in the lever arm as the cable moved back and forth. And why would the leave so much room between the head of the bolt and the hole? If it were meant to swivel it should have another hole for a cotter pin, right?

I just did a search online and found this thing called a "B nut" which looks way more like what I need.
