Sorry, not super familiar with the manufacture of bolts, but could you explain what you mean by "compressive strain?"
On another note, in 2012, 2220 used grade 5 stainless 1/2-20 (if I remember correctly) bolts as axles on our robot. We made it the entire season without bending an axle significantly. Not saying it was a good idea, but it worked in our case.
