The Channellock 12" wrench is a convenient and durable addition for your everyday fastening jobs. The opening angle is wider and is therefore also suitable for larger diameter nuts and bolts. The extra-long jaws grip the workpiece better, greatly reducing the risk of skidding or nut damage. These jaws are also thinner, giving you greater access in tight spaces. Finally, the 4-thread knurl provides superior adjustment capacity. This tool comes with a limited lifetime warranty.
