The Bionic Grip™ is an open-ended version of the patented, award-winning Bionic Wrench™. This hand tool brings together the best features of a pair of pliers and an adjustable wrench. Like the Bionic Wrench™, the 8-inch Bionic Grip™ distributes force around a work surface and automatically grips multiple sizes of nuts and bolts. However, the Bionic Grip’s™ open-ended head can go over work difficult or impossible to reach with a closed-headed wrench, including pipes and tubes. It also has four serrated jaw surfaces and a new Interlock™ mechanism that stays locked while under torque load – making it ideal for use on household plumbing or hydraulic and air line fittings.

6 inch Bionic Grip™ replaces 14 metric and SAE wrench sizes, spanning 1/4 inch to 9/16 inch and 7 mm to 14 mm and instantly grips pipes, fasteners and fittings from 1/4 inch to 9/16 inch.

8 inch Bionic Grip™ replaces 13 metric and SAE wrench sizes, spanning 1/2 inch to 3/4 inch and 13 mm to 20 mm and instantly grips pipes, fasteners and fittings from ½ inch to 13/16 inch.

The Bionic Wrench™ is a remarkable patented hybrid of an adjustable wrench with the ease of use of a pair of pliers. In addition, the genius of attacking a bolt/nut on all 6 flat sides removes the stress and strain on the corners of the bolt. This coupled with the superior gripping action of the jaws, allows the user to complete their work without the wrench slipping off and damaging the bolt. The design of the Bionic Wrench™ multiplies your hand's gripping force, so you can more easily tighten/loosen bolts. You can develop ratchet-like speed by fully turning the Bionic Wrench™, release the grip while still on the bolt, reposition wrench, tighten grip-repeat until finished.

6 inch Bionic Wrench™ covers 6 SAE sizes, 1/4, 5/16, 3/8, 7/16, 1/2, 9/16 inch, and 8 Metric sizes, 7,8,9,10,11,12,13,14mm.

8 inch Bionic Wrench™ covers 5 SAE sizes, 1/2, 9/16, 5/8, 11/16, 3/4 inch, and 9 Metric sizes, 12, 13, 14, 15, 16, 17, 18, 19, 20mm.
