There is little information on the bending resistance of bolts because bolts should not be placed in a position where the force applied is perpendicular to the axis of the bolt and off set from the bolts supported length (IE. sticking out between surfaces like in a hitch pin that is loose between two plates. To publish a description of strength when the bolt is used improperly would be a legal mistake. With that said, and with the lack of published data. I took a new 6 inch X 3/8 grade 8 bolt and bent it in a 6 inch Wilton vice by hammering it sideways, with no heat. The bend produced tiny marks from the vice jaws where the bolt stuck out see image, and full hard swings from the 2 pound hammer. A similar 3/8 grade 5 bolt had much larger marks, and less than 1/2 the swings. (I do not have the other bolt, it was scrapped) As can be seen, the bend radius is about a bolt diameter. There is no cracking or surface appearance change on the tensile side. I hereby say grade 8 is as good as it gets for a hitch pin. Jim
