The hitch pin doesn't experience any side-side pressure, only the pin shaft itself bears the load. I think you are concerned about the small locking area on the pin?--That shouldn't be a problem in towing. I have off and on used one of those locking pins on pretty good loads and never had a problem with them, except the lock cover letting dirt into the lock.
