Constructed of durable and heavy-duty chrome vanadium steel, this socket has the strength required for high torque jobs and will fit onto any 1/2-inch drive electric or pneumatic impact wrench, ratchet, torque wrench, extension bar, or adapter. This socket features a rust and corrosion resistant black oxide protective finish and its deep well design allows it to access fasteners in slight recesses without an extension bar as well as nuts on extended bolts.

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.
