The 8-inch Bionic Wrench is a new type of hand tool that teams the versatility of an adjustable wrench with the simplicity of pliers. With a simple one-handed squeeze, the 8-inch Bionic Wrench automatically sizes and grips 16 U.S. and metric-sized nuts and bolts, distributing equal force on all sides of the work. When the handle is squeezed, six hardened steel jaws converge and firmly grab a nut or bolt on all sides. The Bionic Wrench will not slip or round off nuts and bolts like other gripping tools. Users can tighten or loosen their work with ratchet-like speed because there is no need to remove the wrench from their work between turns.
