The Klein Tools 7-Piece Magnetic Nut Driver Set is made with chrome-plated shafts to help prevent corrosion. The shafts are hollow and provide ideal operation when working on electrical panels, HVAC/R panels and stacked circuit boards. The nut drivers are made with donut-shaped magnetic tips to easily hold fasteners securely in place. The Cushion-Grip handles provide greater torque and are color-coded for easy identification of compatible tips.
