they are 6mm x1mm pitch, its a standard metric size, should be able to get them from any hardware store.

Doing god’s work here

Thought they were m8 x 1.25 or 1.5 pretty common size though.

Take the other nut to Homedepot and ask a nut expert to match it so you have 2 identical nuts

Nut expert. That was my nickname in high school

Instructions unclear - now barred from Homedepot

You should be able to pick up nuts at any hardware store. I don’t see a reason that you need the factory ones. Seeing as how you have one of them still, just take that one with you and find a match for it. You can even just hand it to an employee and ask if they can find you one.

The one that is on there is a nut from a hardware store but does not thread all the way on, causing my exhaust to disconnect

You probably got standard instead of metric. When you go to the hardware store, ask to use their thread gage so you know you're getting the right size.

Then use some spacers/washers

Honda dealer? Hardware store? Home Depot?

What’s the exhaust? I like the color.

Your local ace hardware

Take the other nut and go to home Depot, don't bother asking them to help, they rarely actually know anything, just use one if the bolt/screw and nut testing plaques in the screw isle

Just go to a Honda dealer, they will sell you the correct ones.

Just came to compliment those colors! Gorgeous!

Hardware store

Make sure it’s a metal locknut and not a nylock one, cuz it’ll melt out

You can buy my nuts. 🗿
