Default Bolt/thread size?

Can someone please tell me what the thread size is on the majority of 13mm headed bolts on Cossies? I need to get a kit to re-thread one of the lifting eye bolt holes in the head!
Cheers Spadge...

Hopefully the answer will be on here soon mate!
I need to get a Heli coil kit to suit and i believe they come in M sizes so need to know which one to get?
The majority of the 10mm headed bolts are M5 on a heicoil kit.

There isn't a standard 13mm size in afraid, chances are its 1/2 inch, which means it could be bsw, bsw fine, unc, or unf, or mabey npt if its a tapered thread. That probably didn't much really , sorry to complicate things. I have all the charts and a zeus book here at work as I'm an engineer. Can you tell me how mant threads there are per inch?

Yeah, Iv'e just made an arse out of myself , oh well, use to it by now. I missed the 13mm HEAD bit, I thought you meant 13mm thread diameter. Jus measure the thread dia and that is the thread size.
