Give yourself the reach you need regardless of whether it is only an extra few inches or an entire foot with the STEELMAN 61151 8-Piece 1/2-Inch Drive Impact Extension Set. This set includes 7 different sizes with compact and extra long lengths available. Each is forged of high strength chrome-vanadium steel with a protective black oxide coating that provides increased rust and corrosion resistance. Laser etched markings indicate drive size and length and will not rub off or wear away with use. A spring-loaded detent ball on the end of each extension bar helps keep attached sockets and adapters in place. Set includes the following sizes: 3-inch, 4-inch, 5-inch, two 6-inch, 8-inch, 10-inch and 12-inch. When not in use, the extensions fit into the included blow-molded plastic storage case for easy transportation and organization.
