I have seen a few things out there, but I never bookmarked any.  One I 
do remember, although a bit oblique, is that the Fisher Plow pdf's of 
instructions and part lists for old plows have guides to SAE bolt head 
markings on each one.  They are a little weird to navigate to, and the 
site doesn't work on Mozilla, have to use IE.

Here's a rndom one, bolt guide is on last page:

Metric markings are different, however.

I bet googling "bolt head markings" would get you there pretty quick, 
though.
