Might try a grade 8 like others have said in this size.
M10x1.25 x 25 or 30

IIRC

 

won't 1.25 be too big? Forgive my ignorance

 

just get the bolt for like 50 cents whats the worsejust retap it

 

Home depot did not have anything even close..I checked and caliper is not stripped as the other bolt hand tightens just fine. Dealership it is, sucks cause tomorrow is a holiday here so no car til tuesday, what a stupid .50c problem to have

 

Thread Pitch is 1.25

Here is a metric bolt chart printable in full scale

 

its 1.00, even when I hold the bolt up to your chart 1.25 is big.

 

Good deal then, glad your getting it sorted out.
