The CHANNELLOCK® 810W 10" Wide Adjustable Wrench has a greater jaw capacity to support larger nuts and bolts with thinner, non-protruding jaws for greater access in tight spaces. The combination of a smart and comfortable tapered handle design, precise 4-thread knurl and minimal head width improves performance in everyday use. CHANNELLOCK® Adjustable Wrenches are made in Spain and forged from rugged chrome vanadium steel.
