Mac Tools has unveiled the new Knuckle Saver Wrench lineup with design enhancements that offer greater performance and comfort. The updated Knuckle Saver wrenches include improved strength, durability, corrosion-resistance and cleaning capability. The new forging provides a wider shank that adds additional strength for improved performance. The shank also has a new curved side edge for enhanced comfort, while the standard length has been increased for added leverage in tough applications. The box end of the wrench was strengthened to provide technicians additional support when tightening or loosening fasteners. The open end continues to feature the Knuckle Saver design to provide 400 percent more contact area than a standard wrench. The revolutionized wrenches also incorporate stronger chrome plating for a more durable and corrosion-resistant finish that’s easier to clean.
