Any bolt that fits will be fine. As previously mentioned, the square head is a convenience (and a minor safety feature) that allows the use of one wrench to loosen/remove the nut.
The corrosion should be of more concern. I would recommend removing the battery to look for corrosion beneath it, then washing the battery compartment and the battery if necessary with a thick, almost paste baking soda solution to neutralize the leaking battery acid and vapor. A coat of Rustoleum in the battery compartment may be needed. Also, check to ensure your battery vent tube is in place. If not, make it so.
Go back to your Pep Boys for a pair of those red and green felt collars to go under your battery cables to prevent future problems.
