Winner of a Popular Mechanics Editors Choice award, this is the tool that combines the versatility of an adjustable wrench with the simplicity and ease of use of a pair of pliers, surrounding a bolt or nut on all sides to grasp up to 30X more surface area than typical wrenches or pliers for increased gripping efficiency with reduced effort. The patented six-sided mechanism eliminates guesswork when choosing wrench size, fitting both metric and SAE size bolts, and eliminating stresses normally exerted on the corners of a bolt by standard wrenches, grasping powerfully without slipping or damaging the bolt surface. The cushioned squeeze handle multiplies your hand strength, making it easier to tighten and loosen, and the wrench can be quickly repositioned on a bolt simply by releasing the grip, turning, and re-gripping, allowing you to develop tightening and loosening speed similar to a ratchet. Hardened, cold-rolled steel-laminate construction has a black oxide finish that resists rust, corrosion, and chipping. 6" wrench works on SAE sizes 9/16, 1/2, 7/16, 3/16, 5/16, 1/4, and metric sizes 7 to 13 mm.
