Over the years I acquired a set of hooks that had two bolt holes in them they are 1/2 inch hooks I bolted them on then welded them on. They work great for 3/8 chain as well.
I have welded on hooks that were just for use with a pin to the chain, I ground the outside flat and welded them on then tested them with the max lift of the loader.
You never, ever rely on a chain, Never, do you position your self were if the chain breaks it can hit you. That is Russian Roulette, most times if I am pulling a heavy load, I put an old canvas tarp over the chain, I am just not in to that pain and agony stuff.
Just a thought!
