SATA GL22201 3/8" Drive Hex Bit Socket 3mm

Key specs include: 3mm hex bit size, 3/8" drive, chrome vanadium steel body, S2 steel insert bit for maximum strength, chrome-plated finish for corrosion resistance, heat-treated for durability, large stamped size markings for quick identification, and compatibility with standard 3/8" drive ratchets and torque wrenches.

Compared to other sizes, this 3mm hex bit is ideal for smaller fasteners where precision fit matters. If you need a larger or different drive size, check these nearby options on Fepy to compare fit and capacity: https://fepy.com/products/sata-gl22202-38-drive-hex-bit-socket-4mm and https://fepy.com/products/sata-gl22301-12-drive-hex-bit-socket-8mm. These alternatives offer different hex sizes and drive configurations while maintaining Fepy’s typical build quality.

It's well-suited for automotive tasks involving small 3mm hex fasteners, precision furniture assembly, bicycle maintenance, electronics chassis work, and any project requiring accurate engagement with small hex bolts while using a 3/8" drive.

1) Attach the socket to your 3/8" drive ratchet or torque wrench. 2) Align the 3mm hex bit with the fastener and push straight on to ensure a snug, square fit. 3) Apply controlled torque—avoid sudden or sideways pressure. 4) Remove once the fastener is seated or removed. Always use the correct torque for the fastener type and material.

Yes. It uses chrome-vanadium steel for the body, a chrome-plated finish for corrosion resistance, and an S2 steel insert bit for added strength. The combination is heat-treated to extend tool life and endure repeated use.

The design emphasizes a precise 3mm hex fit with a snug engagement to minimize cam-out. The precision-machined bit and flat-side contact help reduce rounding and wear on both the tool and fastener when used correctly.

This socket is optimized for non-impact use with a ratchet or torque wrench. Using it with an impact driver can cause premature wear or damage; reserve impact tools for impact-rated sockets designed for that purpose.

Its combination of a precision 3mm hex bit, robust chrome-vanadium body, S2 insert bits, corrosion resistance, and clearly marked size indicators delivers reliability, longer life, and time savings on the job—especially when you need a dedicated 3mm hex engagement in a 3/8" drive system.

Keep it clean and dry after use, wipe away oil or residue, and store in a protective case or tray to prevent nicks. Periodically inspect the bit for wear, and avoid dropping or striking the bit against hard surfaces. Lubricate the ratchet interface if needed and use it within intended torque ranges.

The socket features large stamped size markings for fast identification. Check the 3mm hex marking on the bit to confirm compatibility with the fastener before applying torque.
