Whether you work in the automotive industry or just need to repair some furniture or an appliance, the STEELMAN PRO 78523 15-Piece 3/8-Inch Drive 6-Point Metric Socket Set will always come in handy. Constructed of durable heavy-duty chrome vanadium steel, these shallow depth sockets have the strength required for high torque jobs and will fit onto any 3/8-inch drive ratchet, torque wrench, extension bar, or adapter. The sockets all 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. 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. 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 fade, wear away, or rub off with use. Set includes the following metric sizes: 7mm, 8mm, 9mm, 10mm, 11mm, 12mm, 13mm, 14mm, 15mm, 16mm, 17mm, 18mm, 19mm, 20mm, and 21mm. Rated to meet or exceed ANSI / ASME performance requirements for hand tools, these can handle tough use in any professional or home shop / garage.
