Wheel Hub Bolts
 

Does anyone have any tips for sourcing rear wheel hub bolts? I'm replacing rear wheel hubs and one of the bolts is rounded off.These are not the wheel studs. I like to never got it out. So, I'd like to replace it with a new one.
I went to the local Acura dealership and they found one in Chino California and its a week out. My daughter is driving the car for work and its tore down in my garage.
Its a 2006 Acura TSX. I think the Honda Civic uses the same parts?
I'm new to the site so excuse me if I posted this to the wrong section.
Thanks in advance

Per this website the bolt is a M10 x 70mm long (Item 36). It's probably a M10-1.5 (1.5 mm per thread).
Put the new and old bolt side-by-side to see if the treads are the same.

Bring bolt to a hardware store, Home Depot, or Lowes and look for this size bolt. Make sure you get the same length or slightly longer (~75mm). You need grade 8.8 minimum or grade 10.9 if available. DO NOT use any bolt that isn't labeled 8.8 or 10.9.
You will also need a M10 washer since this bolt has a flange.

Honda uses a 1.25 thread pitch. They're all JIS bolts.

M10x1.25 is going to be hard to come by in a FLANGE bolt and class 10.9. Try McMaster Carr.

I would not use anything except a flange bolt in a Class 10.9.

Class 8.8 is a very bad idea. They're equivalent (roughly) to a grade 5 SAE bolt.

Look for the part number on bernardiparts.
Take the part number to your local Honda OR Acura dealer if you need it right away.

Yes, turned out to be a Class 10.9 M10-1.25x70mm flange bolt.I fiqured that out by visiting every hardware store/auto parts store in town. I had to order it from Acura. A week out from California.
I probably had 6 hours in time looking for that bolt. Fastenol could order it too.
Thanks for the help.
