The LOGGERHEAD Bionic is a hand tool that combines the best features of a pair of pliers and an adjustable wrench. This 8-inch tool distributes force evenly across the work surface and automatically grips nuts and bolts of various sizes, relieving stress and strain on their corners. The wrench is fully adjustable with a one-handed push and has increased gripping power for ease of use and adjustment. It prevents slipping, stripping, rounding of fasteners and won't scratch work surfaces, so it's great for soft materials such as plastic, copper and aluminum. Universal design features, combined with improved ergonomics, allow the tool to be used in either hand in any position. In addition, the tool is capable of removing nuts and bolts damaged by other tools.
