Bolt size?

GaryS · Dec 19, 2012

After a couple days of unusual steering sensations, I looked under the hood and noticed that on my power steering pump, there was one bolt loose and about to fall out and another that had fallen out.
Without pulling the bottom bolt I would like to know what size the two bolts on the left (drivers) side are. I am assuming that both upper and lower are the same size. The lower has a 14 mm head. (or at least it seemed like it in the dark)

No AC on this kick....if that matters.

Thanks!!!

I'll hazard a guess and say 10mm x 1.25.

The 10mm bolts I found at a hardware store last night did not have 14mm heads. I don't know how much difference that makes.

Suzuki/Geo uses JIS (Japanese Industrial Standard)

10mm x 1.25 bolts/nuts are flanged and have a 14mm wrench size.

EDIT: I think regular 10mm bolts/nuts have a 17mm wrench size.

It turns out that it is 10mm fine thread. The bad news is that the bolt I thought was missing is broken off inside the hole.
Can you spell e x t r a c t i o n?
