Cylinder head Acorn Nut

Trying to confirm the cylinder head acorn nut size is M12 X 1.75? I would like to clean them up with a tap...have I know its a M12 nominal diameter, anybody know the thread pitch? Either 1.5 or 1.75...

Thanks!

How to clean the acorn nuts?

Certainly someone has cleaned the years of crud off the acorn nuts and bolt studs with a tap and die. There was even a thread about oiling the acorn nuts and torque. I personally thought the oil was added so the nuts don't get galled to the bolts. These nuts are dirty and full of crud- that most certainly would affect the torque.

Also good to know they are the same as the wheel nuts. I'll have a spare if I ever lose one.
