[AT] Battery Cable Lug question

[Dave Rotigel]

I could be wrong, but I suspect the bolt is brass (or copper plated),  
not copper. See: http://www.mcmaster.com/#brass-hex-head-cap-screws/ 
=dkqbc6 In any event, any steel bolt will do just fine and although  
copper or brass is a better conductor of electricity you will notice  
no difference if you use a steel bolt. The grade of the bolt will make  
no difference.
