Every mechanic knows the importance of having a reliable set of tools, and the STEELMAN 99922 8-Piece 1/2-Inch Drive SAE Deep Impact 6-Point Socket Set was made to make your life easier when working on cars, trucks, or any job in the workshop. Constructed of chrome vanadium (CrV) steel for strength and lasting durability, these sockets have a rust and corrosion resistant black oxide protective coating to further extend their life. Their 6-point design grips the sides of fasteners and not the corners, reducing wear and the chance of slippage or rounding the fastener. Thanks to the socket's deep design they can easily reach nuts on extended bolts and those located in small recesses without the need of additional extension bars. Set includes 1/2-inch, 9/16-inch, 5/8-inch, 11/16-inch, 3/4-inch, 13/16-inch, 7/8-inch, and 15/16-inch SAE / standard sockets. When not in use, the sockets can be stored on the included clip-on steel storage rail for easy organization and portability.
