Atnn Fast Ed/others Specs on 15mm Water Pump bolt?

Hi Tom

By 15 mm, I'm assuming that you mean the size of the head of the bolt. The thread is going to be 8 mm coarse thread, which is 1.0 pitch I believe. The Ford hardware catalogue doesn't show the grade for that one, but it may be marked on the head of some of the other pump bolts. 8.8 or 9.8 hardness should be fine.


cheers

Umm wouldn't the coarse thread for an 8mm bolt be 1.25? I think the medium thread is 1.0. That's what I was told while I was recently buying some intake manifold and exhaust manifold bolts.
 
Thank you for the affirmation. I still havent had a chance o get a new one...(work and weather!!)
Now o just get that broken bolt out of there! :mad:
