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...

 

When you find out spadge, can you let me know too please as i need to do the exact same thing!

 

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.

 

m8 x 1.25

 

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?

 

you got that wrong

standard size list for you
4mm thread 7mm spanner
5mm " 8mm ""
6mm "" 10mm """
8mm """ 13mm """"
10mm """ 17mm """""
12mm """" 19 """""

yes spadgerdo but dont forget the 1.25 pitch
lets just check whats gone wrong mate i dont wana confsue you but like antil roll bar on front use 13mm head but has a 10mm thread

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.
