I make my own Hitch Pins out of Cold Rolled Round rod.
They do not break at least I have not had one break yet.
I have bent several but not to bad to be able to tap them out of the receiver with a hammer.
They rust up a bit when sitting in the Weather

I am to Cheep to pay the price for store bought Hitch Pins.

Cut the length you want them. Drill a hole in each end Spin a taper on one end and put a large Key Ring for pulling on the other end.
