Every mechanic knows the importance of having a reliable set of tools, and the STEELMAN 55440 16-Piece 1/2-Inch Drive Metric 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 impact sockets are hardened to resist drive end round out for a lifetime of dependable use. The socket's high torque, 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. The sockets each feature a rust and corrosion resistant black oxide protective coating with easy to read laser etched size callouts and markings that won't rub off or wear away. Set includes 10mm, 11mm, 12mm, 13mm, 14mm, 15mm, 16mm, 17mm, 18mm, 19mm, 20mm, 21mm, 22mm, 23mm, 24mm, and 25mm metric sockets. Rated to withstand up to 150% of ASME torque requirements for impact tools, these can handle tough use in any professional or home shop / garage. When not in use the sockets can be stored in the included blow molded plastic storage case for easy organization and portability.
