Good info here (above) and a valuable reminder... FYI, most of the stainless bolts available at your local hardware store are grade-4; OK in many applications, but not good for high stress.

I agree in spades, Jim. And although "high strength, corrosion resistant" bolts are close to twice the strength of the regular SS bolts offered, they are still only slightly higher in strength than a Grade 5 CS bolt. For critical, dynamic service a Grade 8 CS fastener is the right choice. Use SS for non-critical services where you want the "bling" of a polished fastener, not where you're relying on it for safety.
