The extended reach design and longer shanks deliver improved visibility and reach. 360-degree rotating back caps offer greater control, driving ability, and tuning. The color-coded markings allow you to easily identify screwdriver bit types on the jobsite. Chrome-plated shanks increase tool life by reducing corrosion and providing superior rust protection.
