Hi, this is my first post
I am doing some work on my civic replacing bearings because of rod knock and have lost two of the connecting rod nuts on my 03 Honda civic ex part number 13205-634-010. I'm trying to figure out the thread size on it so that I might be able to find a cheap replacement in my area but it seems to be smaller threading than anywhere I've checked so far carries.
Hopefully I can get an answer soon

 

So, you aren't willing to spend $9 to fix your car ??? SERIOUSLY ??? Even if you could find a replacement nut at your local hardware store or nut-and-bolt house... what do you think your chances are of finding something with the proper engagement surface and the same (or stronger) material composition ???

I am not sure the exact size, but I believe it is either 9mm or 11mm x 1.0 pitch.

 

Its not that I'm not willing to spend that much its that I cant find anything local that has it in stock and I'm trying to get it fixed asap

 

These were your words, not mine. What about a salvage yard where you could rob a couple of nuts from an existing engine then ???

 

Do NOT use hardware bolts. The grade won't be the same. From my experience, my Honda dealer will have them the next day .
