Locking pliers were an incredible invention. The term "Vise Grips" is actually a brand name for the original locking pliers, but it's been worked into auto repair lingo so well that nobody ever actually says "locking pliers." Vise Grips can be used to hold onto anything really tightly. While we wouldn't suggest using them for holding onto spouses or children, just about anything else is fair game. They come in really handy if you have a very stubborn bolt, or a bolt that has been stripped or is otherwise damaged. Just adjust them, lock 'em in place, and nine times out of 10, you'll have it loosened in no time.
Remember, Vise Grips shouldn't be your go-to tool when you need to remove a nut or bolt. They are a last resort. While they can really grab a tough nut, Vise Grips may also damage it, leaving marks and rounded corners meaning you can't use the nut or bolt again.
