I need longer studs for my new starter. The original studs are M10 X 1.5 pitch.
I purchased new longer studs also M 10 X 1.5.The strange thing is that the new studs will not thread into the bell housing. ½ turn and they bind. My first thought was the pitch is wrong. But the test gauge at the hardware store and using a M10 X 1.5 nut shows that they are the same and correct.
So why would the OEM stud thread back in by hand and the replacements will not. But the size and pitch are the same?
