I was unable to find data on the grade of the bolt that is used. I found out that Category 4 three point hitch lower arms use 2 inch diameter lower link pins.
I am not aware of published data on the strength of the standard ball hitch with is also utilized in single shear.
A shorn coupling of any type would have disastrous consequences. It seems to me that the socket part of the coupler is also likely to fail in the even of suddenly stopping such as in a collision.
