QUICK! Stock Exhaust Flange Nut Size

I need to replace the nuts that thread onto the studs on the stock G37 exhaust. Anybody know the correct size/pitch? Dealerships only have part numbers and could not tell me.

They're 14mm. Not 100% sure of the thread pitch. Probably 1.25.

Then it will be 1.0. If you have one of the bolts available, take it to Lowe's or HD and use the template they have on the bolt aisle. It'll screw into th one that's the right size.
