Harmonic balancer bolt spec's?

[JAyers93]

Anyone know the thread pitch on the harmonic balancer/crank bolts? I need to find some about 1/2in longer.

Did a search but couldn't really find anything.

Thanks

I'm fairly certain they are m12x1.25 but I can't find my McMaster-Carr invoice. I know they are a very fine thread that's hard to find without ordering big quantities.

They are 12mm x 1.25 pitch.
