1/2" Pneumatic Impact Socket | Cr-Mo Steel | Black Phosphate Finish

Product Overview

The 1/2" Pneumatic Socket is a professional fastening tool designed for pneumatic impact wrenches, air impact tools, and compatible impact driving equipment. It is used for tightening and loosening nuts, bolts, and other hex fasteners in automotive repair, machinery maintenance, equipment assembly, industrial production, and construction applications.

The socket body is made from high-quality chrome-molybdenum steel (Cr-Mo), a material known for strength, toughness, and impact resistance in high-torque and repeated fastening applications. The product is fully heat treated through a high-temperature quenching process to support hardness, wear resistance, and long-term operational stability.

A black phosphate surface finish helps reduce the risk of rust and corrosion. The socket features a hex profile with rounded internal corners, helping improve engagement with nuts or bolt heads while reducing the risk of slipping, corner wear, and fastener damage.

Socket size, length, wall thickness, outside diameter, compatible fastener size, and torque capability should be confirmed according to the specific model and application conditions.

Use and Maintenance Tips

Confirm that the socket size matches the nut or bolt size before use.

Ensure that the socket fully engages the fastener and avoid angled operation.

Use with compatible 1/2" square-drive pneumatic impact wrenches or impact tools.

Do not use sockets that are cracked, deformed, heavily worn, or dimensionally damaged.

Do not use the socket for prying, striking, bending, or other unintended applications.

Do not force a mismatched socket onto a fastener.

Clean oil, moisture, dust, and metal debris from the socket after use.

Store the socket in a dry and clean toolbox or storage case.

Safety glasses, gloves, and other suitable personal protective equipment are recommended when operating pneumatic impact tools.

FAQ

1. What does 1/2 inch mean?

The 1/2" specification generally refers to the square drive size. It is designed for 1/2" or 12.7 mm square-drive pneumatic impact wrenches, air tools, and compatible tools. The actual socket opening size, such as 17 mm, 19 mm, or 21 mm, should be confirmed according to the specific model.

2. What are the benefits of a Cr-Mo steel socket?

Cr-Mo steel offers good toughness, hardness, and impact resistance, making it suitable for high-torque and repeated fastening or removal tasks. This material is commonly used for impact sockets and pneumatic tool accessories.

3. Can this socket be used with a standard hand ratchet?

If the square drive size is compatible, the socket can generally be used with a 1/2" hand ratchet, breaker bar, or torque wrench. Please confirm that the socket, tool, and fastener specifications are compatible before use.

4. What is the difference between a short socket and a deep socket?

A short socket is generally used for regular nuts and bolts and has a more compact structure for convenient storage. A deep socket is better suited for long threaded studs, recessed nuts, or fasteners requiring greater depth. Selection should be based on fastener position and available working space.

5. Do you offer OEM/ODM customization?

Yes. OEM/ODM services are available for logos, size engraving, metric or SAE specifications, socket combinations, storage cases, color boxes, labels, barcodes, and export cartons. Please provide your estimated order quantity, size list, target market, and packaging requirements for evaluation.
