Cant find me thread gauge anywhere in the house, sure it will turn up eventually.............so

 

Can anyone tell me pitch size of the M10 engine mount bolts please, pretty sure it's 1.25 pitch but need to verify as i'll have to buy a tap to clean up the threads, looks like they got gunked up a bit during vapour blasting and wont take a bolt without forcing it...

 

Will have to replace all the bolts as well as they are proper mullered, dont know how they were ever torqued correctly...

1.25, be careful the thread does not end up oversized or it will be prone to stripping.

If it does I have various length helicoils to fix it.
