Bill,

3/8" chain would plenty for safety chains. Yes the hook is equally important (they are graded as well), that's why the new term is system 7, referring to a match set of equal strength components. Grade 80 is not designed to absorb shock, so yes, system 7 is the best for towing applications. I use grade 8 bolts and nuts with thru-hardened washers to attach them to my trailers.

Hint: If your going to buy some system 7 chain and hooks, call your local heavy duty truck parts dealer and ask for transport tie downs in system 7. He should have them in 5/16" & 3/8" in either 20' or 25', You can buy a chain assembly with 2 hooks cheaper than you can buy the chain by the foot
