The Bionic Wrench is unlike any wrench you've ever seen before. In fact, it looks and works more like pliers than a wrench. This cleverly designed tool has a pair of spring-loaded handles and a circular head that's fitted with six hardened steel jaws. As you squeeze the handles, all six jaws slide toward the center and lock onto the head of the nut or bolt. This unique mechanism allows the Bionic Wrench to grip hexagonal, square, and even rounded fasteners. This ruggedly built tool is made of hardened, cold-rolled steel and features a rust-resistant black-oxide finish.
