SATA SC25201 1/2" Drive Long Hex Bit Socket 4mm

Key specs include: 1/2" drive compatibility, 4mm hex bit size, extended (long) socket design for better reach, chrome-plated corrosion resistance, laser-etched size markings for quick identification, and laser-etched, precision-machined engineering for a precise fit.

A long-reach socket gives you access to fasteners hidden in deep cavities or recessed areas where a regular socket won’t reach, improving leverage and reducing the need for extra extensions or adapters.

It is designed for 1/2" drive ratchets and torque wrenches, making it compatible with standard 1/2" drive tool systems used in automotive, mechanical, and DIY applications.

Insert the 4mm hex bit squarely into the fastener, align the socket with the drive tool, and apply steady torque within the tool’s rated range. Use a properly sized breaker bar or torque wrench as needed, and avoid using excessive twisting forces that could wear the bit or socket.

Yes, the socket is designed to be impact-ready for heavy-duty tasks. Use it within the torque capacity of your impact tool and ensure compatible accessories are rated for high-torque operation.

Ideal for automotive repairs, machinery maintenance, bike work, appliance service, and any task requiring reaching fasteners in tight or recessed spaces where a standard socket can’t reach.

The socket features large laser-etched markings for easy size identification, so you can confirm the 4mm hex quickly without guessing.

Keep it clean and dry after use, wipe away oils or debris, and store it in a protective case or organizer to prevent corrosion or impact damage. Avoid exposing it to harsh chemicals that could degrade the chrome finish.

These offer variations in size or length to suit different fasteners and spaces.

Compared with standard-length hex sockets, this long socket provides greater reach to access recessed fasteners while maintaining the same 4mm hex engagement. It shares the same 1/2" drive compatibility and robust build, but the extended length improves accessibility in tight areas.

Consider reach (long vs standard), material and heat treatment for durability, chrome finish for corrosion resistance, and laser-etched markings for quick size recognition. If you frequently work in tight spaces, the long-reach design offers better efficiency and fewer tool swaps, making it a better value in such tasks.
