This has been discussed here before but I don’t think I could find the thread.
It seems most feel that a grade 8 bolt is designed for its strength to be in tension and not in shear like a hitch pin is made for. The thoughts were a G8 would shear and the hitch pin being softer, for lack of a better term, would bend slightly therefore absorbing the shock better.
There is a YouTube channel called Matt’s Off-road Recovery where this guy jerks vehicles out with recovery ropes every day in a commercial recovery operation and he appears to use hitch pins.
