What size nut is this?

[Snellgrovia]

I went to replace the belts the other day and noticed I don't have a nut on my tensioner for the Alt/A/C belt (91)....the back one has one, but the front one is missing and it's making my pully ****-eyed and it's tearing into the belt. Does anyone know the exact size I would need or a part # I can ask for at AutoZone or something?

Thanks

I'm farily certain it is an M10. I am not sure of the thread pitch, but for the few pennies each, you could get nuts in both the fine and coarse metric pitches. The OEM nut had a captured washer on the inner face. It may be prudent to also get am M10 stainless washer.

Just as a suggestion, get a lock nut. rangerj

well, the M10 course was the correct one (for future refrence), but it didn't go all the way down the bolt. so, I just but some lock washers and regular washers on it with some lock-tite and it seems to be holding well. The belt is now parallel with the pulley, which was not the case before.
