First you have the case, then the warning tag, then the fiber insulating washer, flat washer, lock washer, nut, another lock washer and then another nut. You are correct, there is no good way to secure it. The hole is almost as large as the fiber insulating washer. The best fix is a different warning tag with a center hole just big enough to fit over the terminal stud. I will PM you my website so you can see one on there under misc. parts. With this tag the insulating washer holds it down secure.
Will PM you.
