It's metric of course, most bolts I think are 1mm pitch, the axle bolt is pretty huge, maybe like 14mm? Actually.... Looking up the dust seal on the bearings, the axle size there is about 23mm, pretty sure it tapers down a little, so probably between 20-22mm. I've seen some larger bolts be 1.25mm pitch, so should be in the general ballpark, but a caliper will be a lot more accurate to measure it.
