UCA Pivot locking nut dimension

[MVRight]

Working on installing the UCAs and one of the locking nuts is missing. The bolt is tight on the pivot hole where the rest are slide easily. Think the bolt wasn't quite all the way in and the locking nut wasn't on tight and was lost in shipping. Figure I can clean up the hole, but need a replacement nut. It is only one, what's the size and type I need for the replacement? Thought I found the answer on the other site, but now I can't find the post. Thx

M12 grade 10.9 locknut

Quick verification, I measured one of the other of the two remaining nuts. The diameter across the flats of the nut is .556 or 14mm. 14mm socket also fits fine on the nut. From what I see on the web, an M12 is 19mm across the flats. The lock nut I'm missing is one of the 3 for the pivot arms on the front UCA. Just want to confirm the size of the lock nut.

Thanks!
