This magnetic nut driver has an adjustable shaft that lets contractors change the length of the shaft from 3 inches up to 6 inches in length. Push-button action releases the retractable shaft and locks it into position, allowing users to adjust the length of the tool to get into hard-to-reach areas. The magnetic end allows for precise placement and helps to avoid dropped hex screws. The hex nut driver is available in ¼-, 5/16- and 3/8-inch sizes. The driver also has molded grip handles that are color coded by size.
