Lots to do with metallurgy and the properties of the bolts. Grade 8 bolts
are brittle and snap eg in a shear loading whereas an aircraft AN bolt
doesn't offer much more in the way of tensile strength but will withstand a
much greater load in shear and then will bend rather than snap.

depicted. Not sure what this has to do with fasteners, but there must be a
lesson there somewhere about metallurgy.
