The STEELMAN 55457 11-Piece 3/8-Inch Drive 6-Point SAE Socket Set contains a selection of the most commonly used standard sized shallow sockets to help with a wide range of repair and maintenance projects. 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 6-point design grips the sides of fasteners and not the corners, reducing wear and the chance of slippage or rounding the fastener. The sockets each feature a rust and corrosion resistant high polish chrome finish that not only looks good but is easy to wipe clean of dirt, oil, and grime. Easy to read size markings are hard stamped directly into the steel with easy to read laser etched size callouts and markings that won't rub off or wear away. Set includes 1/4-inch, 5/16-inch, 3/8-inch, 7/16-inch, 1/2-inch, 9/16-inch, 5/8-inch, 11/16-inch, 3/4-inch, 13/16-inch and 7/8-inch SAE / standard sockets. Rated to meet or exceed ASME torque and performance requirements for hand tools, these can handle tough use in any professional or home shop / garage. When not in use the sockets can be stored on the included clip-on style metal socket rail for easy organization and portability.
