Klein Tools' extra-wide jaw 8" adjustable wrench, No. D509-8, features a full 1-1/2" jaw capacity, the same capacity as a standard 12" adjustable wrench. The shorter handle makes it easier to reach nuts and bolts in confined spaces. The tool has a minimally protruding jaw shank that also provides greater capacity in tight spaces. A unique 4-threaded knurl worm gear helps balance this wrench for smoother operation and it allows the user to apply up to 30 percent more force. It comes with standard and metric measurement scales for faster adjustment and a wider handle for added comfort.
