The dual-pawl technology on the Husky 100-Position Double Ratcheting Wrench Sets provides access to engage fasteners where other wrenches can't with their ultra-narrow, 3.6° arch swing box-end. Their 10% longer beam provides increased reach for accessing hard-to-reach fasteners and improves overall leverage. The innovative open-end ratcheting design improves the speed of ratcheting and allows access of an open-end without ever removing the wrench from the fastener. The New Husky Universal Combination Wrenches with Surface Grip technology allows you to get tough jobs done. These wrenches feature an innovative Surface Grip open-end design that grips fasteners on the flats rather than the corners. This feature helps to prevent rounding and damage to the fasteners while generating up to 80% more grip than a standard open end wrench. Each long pattern wrench is 10% longer than standard Husky wrenches providing better access to hard-to-reach fasteners. The added length also allows for increased leverage to be applied to the fastener making it easier to break free hard-to-remove nuts and bolts. The universal box-end is designed to be used on 6 different styles of fasteners. Husky Black Surface Grip wrenches offer better grip, better access, more torque and more leverage which makes them a great addition to any toolbox.
