Front brake caliper bolt pitch

I'm being lazy by not taking a bolt out and measuring it but it's pissing with rain here and I have to work outside.

I know the bolt is M10 x55 but I'm not sure of the thread pitch, if anyone knows it. I intend to replace with Titanium.

Anybody know?

AP8152414, M10X1.25X55. pitch 1.25

Perfect and thanks.

Ordered from BSR bolts. Titanium class 5 for £6 each.

And the rear ones are a 1.5 pitch . . .

Yes.

That stumped (easily stumped) me, too.

Naturally, I only know because I ham-fistedly stripped the top threaded hole on the rear plate.

Well, I am now the proud owner of 4 aero grade Titanium bolts. Just need to fit them and trust luigi hasn't overused the industrial strength Loctite he use on one (just one) handlebar bolt.

Might replace the front spindle castellated nut as well. Just for fun.

Luckily for me, I measured the back one, ordered them all and fitted them ones first - the fronts felt (and looked) different so I exchanged them before I did any damage still don't understand why the pitches are different 

And now I want need a titanium castellated spindle nut . . .

you'll need to know the thread pitch.....
