Having reliable and dependable tools can make any mechanic's or maintenance engineer's life easier, so be sure to find a home in your tool box for the STEELMAN PRO 78421 1/4-Inch Drive x 10mm Deep 6-Point Metric Socket. Constructed of durable and heavy-duty chrome vanadium steel, this socket has the strength required for high torque jobs and will fit onto any 1/4-inch drive electric or pneumatic impact wrench, ratchet, torque wrench, extension bar, or adapter. This socket features 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. The socket's deep well construction allows it to access fasteners in slight recesses without an extension bar as well as nuts on extended bolts. 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. A ball detent recess on the base of the socket holds it securely to attached tools to allow for use at any angle. Easy to read size markings are laser etched onto the steel making it simple to identify the socket without the worry that the markings will wear away or rub off with use. Rated to meet or exceed ANSI / ASME performance requirements for hand tools, these can handle tough use in any professional or home shop / garage.
