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 78486 12-Piece 3/8-Inch Drive Shallow Depth 6-Point Metric Impact Socket Set. Constructed of durable and heavy-duty chrome vanadium steel, these sockets have the strength required for high torque jobs and will fit onto any 3/8-inch drive electric or pneumatic impact wrench, ratchet, torque wrench, extension bar, or adapter. These shallow depth sockets all feature a rust and corrosion resistant black oxide protective finish. The sockets’ 6-point design grips the sides of fasteners and not the corners, reducing wear and the chance of slippage and rounding of the fastener. Easy to read size markings are laser etched onto the steel making it simple to identify the socket you need without the worry that the markings will wear away or rub off with use. Set includes the following metric sizes: 8mm, 9mm, 10mm, 11mm, 12mm, 13mm, 14mm, 15mm, 16mm, 17mm, 18mm, and 19mm. Rated to meet or exceed ANSI / ASME performance requirements for hand tools, these can handle tough use in any professional or home shop / garage.
