Yes, go to Autozone, O'Reilly's or Advance and purchase the standard, OEM replacement battery bolt which has a 5/16" hex head. In the tools section, they usually have a handy little battery wrench with a racheting, box head.

The threads in the battery are blind tapped and shallow. Sounds like the bolt you are using is a tad too long. If so, it will bottom out in the battery threads, leaving the cable "loose".
