Mazda 3: What Size Nuts and Bolts for Battery Terminal on Harness?
 

Hi all.

I have a 2004 Mazda 3s. I just discovered the battery was leaking bad and corroded the terminal on my wiring harness. While I managed to scrub off most of it with a brush, I'll eventually need to spray the terminal down with battery cleaner.

I was also trying to remove the nut on the bolt and noticed that none of my sockets fit the nut anymore. This tells me the acid corroded the nut.

So, what size bolt and nut should I get as a replacement? Thanks.
