EP3 Does anyone know the size, pitch and diameter of a rear caliper bolt?

Hello everyone!

One of my rear caliper bolts is looking highly suspect and I want to avoid rounding it off completely.
Does anyone happen to know the dimension, pitch, grading for these bolts?
I can't take the broken one into a nut and bolt shop as I don't live near one and the car is my only form of transport.
Also, Honda wanted £5 for one. I laughed and hung up the phone.
Flanged M12 is as far as I've got so far.

Many thanks!

Luke

Can't say for sure but many bolts on my car are 1.25 pitch.

10x25 @1.25pitch for the carrier to suspension bolt, or 8x32 (suspect also 1.25, possibly 1.0mm pitch) for the caliper to slide-bolt (assuming EP3?) - see https://www.lingshondaparts.com/par...modelid/9814/block/17S5T501/blockref/B__1910/ - parts 38 and 39.

Some Honda parts are ridiculously expensive.
