Summary : The 6-Inch 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 a perfect fit for civil engineers especially.
