I apologize to the original poster for getting a little off topic, but threading a bolt into the side of the battery with a nut on it as shown in the pic actually has a few advantages over the oem setup. To clarify a few things, first, the oem bolt on the cable end with the tiny head is steel, nothing lead threads into the battery. The side terminal of the battery actually has a steel insert in it too. (I just went out and looked at a battery right now. Yes, at 2:21 AM. Up feeding a newborn.) Anyway, so the oem setup uses a short steel bolt to hold the cable end against the lead conductor on the battery. The bolt with the nut does the exact same thing, except it works as a stud instead of a bolt. You thread it in by hand until it bottoms out, and then you tighten the nut against the cable end terminal, clamping it against the battery. So instead of the oem short bolt wearing against the threaded insert in the battery while being tightened up, with your wrench about to slip on that ridiculously small head, the nut rides on the bolt with full thread engagement, not wearing anything out, (and allowing you to use a properly sized wrench on it too.) Yes, it is possible to overtighten the nut to the point where it pulls the bolt out of the battery, but it's more easily possible to overtighten and strip out the oem setup.
