My reference says AN bolts (all sizes) are either type 4037 or 8740 alloy steel (type 8740 is most commonly used), minimum tensile strength 125,000 PSI. The FAA Handbook AC 43.13-1B Chapter 7 indicates a maximum loading of 40,000 PSI when proper recommended nut torque is applied. AC 43,13-1B can be down loaded in pdf format from www.airweb.faa.gov/Regulatory_and_Guidance_Library/rgAdvisoryCircular.nsf which may take a while since this handbook has lots of charts and illustrations. Now for the soapbox: If you are not following the recommendations of AC 43.13-1B or similar document, you will indeed have an 'amateur-built' aircraft.

Tensile Str.,Yield Str.,Single Shear. I have figures for all sizes but am not positive how to interpolate them.
