Default Bolt Size
Not at home to look in the book, but saw that one of the bolts that hold the exhaust flange on is missing. Anyone know what size bolt I need?

Wouldn't you be able to just measure one of the bolts still intact?
Or is the bike at home as well?

I went to the local dealer and they were out of the bolts, but said that they were most likely 5/16" flange nuts. Picked up a few at the hardware store, but they didn't seem to fit. Maybe it was because the bike was hot, not sure. Ideas?

Maybe you got the wrong thread pitch, most likely it is a 5/16-24

I hate when people say "most likely". Only means they don't wanna spend the time to comfirm for you. I'm looking through my manual, but other than telling the torque specs I can't find anything regarding size.

Sorry, bad choice of words, it is a 5/16 - 24, I'm at work and just tried one on my bike. Hope that helps.

Default flange nut ~ HD #7593

If you're talking about the nut and not the stud that the nut goes on, then you need a 5/16-24 Flange Nut (HD Part #7593). The wrench or socket size to tighten the nut is 1/2 inch.

If it is the nut, then ask your dealer if they have the acorn nuts for your OEM mirrors. They are also 5/16-24 and could be used as a temporary fix.

Thanks for the replies! I had some 5/16" nuts laying around but I needed the fine threaded ones.

I put an end to the loose/missing exhaust nut problem by using ARP aircraft nuts. See this thread.
