I was messing around and lost a bolt from the manifold. What size is this bolt and where can I get a replacement. It;s just the nut, not the whole thing. See my pic:

 

10mm head, 6mm shaft size, 1.00 thread pitch. It's a common metric size ... but the chrome cap head you'll probably have to order if that's important to you. Go to a hardware store ... they're common sizes.

And if for some reason my brain is farting (because my car isn't here) and that's the 12mm head, then it's 8mm shaft, 1.25 thread pitch ... but you'll probably find it in 13mm head instead. I'm pretty sure it's the 10mm, though ... check the one beside it and see if the head is 10 or 12 and that'll tell you.

 

you should just unbolt the one next to it and bring it to the hardware store, or if you want, to the dealership

 

Thanks.
