SATA GL34609 3/4" Drive 6 Point Deep Impact Socket 21mm

The 6-point grip engages the flat sides of fasteners, reducing the risk of rounding corners and providing a more secure fit under high torque, which improves durability and performance during heavy-duty work.

A deep socket allows access to recessed or hard-to-reach fasteners, making it easier to work on bolts or nuts that sit deeper within assemblies and improving torque transfer in tight spaces.

The socket is made from high-strength chrome molybdenum steel for durability and wear resistance. It features a black phosphate coating for corrosion resistance and a long-lasting finish.

It uses a 3/4" drive and is sized for 21mm fasteners, with large markings for easy size identification.

Yes. It is specifically engineered to withstand high torque and impact forces, making it suitable for use with impact wrenches in demanding applications.

Align the socket with the fastener, ensure it sits fully seated before applying torque, and avoid side loading. Use appropriate PPE, start at low torque, and gradually increase to the required torque to prevent tool or fastener damage.

Typical use cases include automotive repair (engine bays, suspension components), industrial equipment maintenance, and construction tasks where deep access and high torque are needed.

Compared to shallower or non-impact sockets, this 21mm deep 6-point socket offers better access to recessed fasteners and enhanced grip under high torque. For other options on Fepy, you can explore related deep sockets and impact-rated sockets in the Impact Sockets collection and the 21mm socket listings to find the best match for your toolset.

Prioritize a high-strength material (like chrome molybdenum), an impact-rated design, a corrosion-resistant finish, and clearly marked size indicators. The deep design and 6-point grip are also valuable features for durability and performance in tough tasks.

The socket features large markings for easy size identification, helping you quickly pick the correct tool in busy work environments.

Consider the socket depth (deep vs shallow), the number of points (6-point vs 12-point), the drive compatibility (3/4" in this case), material strength (chrome molybdenum), coating for corrosion resistance (black phosphate), and whether it’s designed for impact use to handle high torque safely.
