ok. my eyesight isnt good enough, but I got a better set of eyes to look at it and she said it says "10.9" and "eta" and the rest she cant read. i can get that at an ace?

I feel really stupid that I haven't already learned about this.

grade 10.9 is an alloy steel bolt, quenched and tempered. I have no idea what the hell ETA is. Its also means its metric

ok quick search of the old intraweb and I got this

Even among professionals, the ETA is not particularly well known. One of the reasons is the complexity of the system; the ETA for metal anchors consists of 12 alternative options. Each option consists of a certain amount of tests to be performed on the product. In option 1, many different properties of the product are tested, whereas in option 12 just a few properties are tested. This means that products in option 1 have much more official data available on their properties than those in option 12. In other words, an option 1 product is more transparent in terms of its possible range of applications.

Is there a Fastenal near you? You could walk into their storefront and get the bolt you need in a flash.

Good to know...

OP must be hulk to break that bolt!

I barely applied any pressure and it snapped! makes me really nervous about the rest of the caliper bolts. I think the car has been through it's 3rd brake pad change so I guess it was just it's time to go.

I wouldn't think so, since the P/N you get from Ford might not correspond to Fastenal's part numbers... Just take the bolts you have with you and they can identify them from there.

The bolts may be suffering from heat fatigue. Bolts are not really expensive. Since you're doing a brake job (I assume), I would replace the set. 4 bolts can't be that expensive. Better to be safe . . .

It's not always about the strength of the bolt. Some bolts are specifically chosen to be softer than what they are screwing into so that they break before threads get stripped or to prevent galling. With all but the most generic fasteners, it's better to get them from the dealer, at least for newer cars and specialty components.
