On anything that I am questioning, I go with Grade 8.

Speaking of shear strength, in a real world test, we have a large bush-hog that has a "shear" pin in the drive-shaft.

With the big green tractor ahead of this thing, we were forever having to replace the 7/16" Grade 5 shear-bolt.

I got tired of this and replaced it with a Grade 8 and it has not sheared in years; so, so much for the shear strength theory.

If I were concerned, I would use three Grade 8 and three Grade 5 on each side of the plate.

I have (4) 3/4" grade 8 bolts in mine.

I don't believe I said a Grade 5 bolt was stronger in shear - my point is that it has greater ductility. By increasing the strength of the shear pin, you may well find the next weakest link in the mechanical chain should you ever hit a large rock or stump.
