SATA GL13706 1/2" Drive External Torx Socket E20

Key features include an off-corner loading design to reduce fastener rounding, large markings for easy size identification, a thin-wall design with precise nut-end dimensions, and a chrome-vanadium steel construction that’s heat-treated for durability. The chrome plating adds corrosion resistance as well.

E20 refers to the external Torx size. This socket is made to fit external Torx fasteners labeled E20. If your fastener has a star-shaped head with the external size labeled E20, this socket should fit securely.

The socket is built for a 1/2" drive and works with standard 1/2" drive ratchets, wrenches, and extension bars.

It’s well-suited for automotive repairs, machinery maintenance, and any professional setting where external Torx E20 fasteners appear, such as engine components, drive systems, and heavy equipment.

Attach the socket to a 1/2" drive ratchet or torque wrench, ensure it sits fully seated on the fastener, apply steady torque, and avoid using excessive lateral force. It’s designed for high-torque applications and can be used with power tools when appropriate.

It’s made from chrome-vanadium steel and is heat-treated for long-lasting durability. The finish is chrome-plated for corrosion resistance, and it’s described as impact-ready for use with impact wrenches.

The socket is clearly marked with the size, including the E20 designation, so you can quickly confirm it’s the correct tool before use.

They differ in the Torx size (E18 or E24) and may be used for different fastener sizes while sharing the same drive interface and general build quality.

Yes. Its large, clearly printed markings and its specific E20 size help it stand out, reducing time spent searching for the right tool on a crowded workbench or in a tool bag.

Keep it clean and dry after use, store it in a case or toolbox slot to avoid nicks, and inspect for wear or deformation before heavy use. Wipe off debris and apply a light protective oil if needed to prevent rust, especially if exposed to moisture.

This SATA socket offers a precise E20 fit, off-corner loading to reduce rounding, a durable chrome-vanadium construction with heat treatment, clear size markings for quick identification, and chrome plating for corrosion resistance—all designed to deliver reliable performance in demanding applications.
