The external star sockets are a female 6-lobe geometry designed for a high-torque fit that resists slipping. These sockets are required for external star (E-Torx®) fasteners, which are commonly found on seat mounts, brake system components, and steering columns.
Large, Clear Markings
Die-stamped markings are permanently impressed into the steel and can’t wear off. They’re designed with large, clear size numbers that are easy to read even in low light settings.
The polished chrome plating protects against corrosion and wipes clean to a mirror finish. The deepest parts of the socket well, where nickel and chrome layers cannot be deposited in sufficient thickness, are protected with an additional thin layer of clear coat, rather than conventionally-used silver paint, to prevent rust.
Secure Drive Tool Engagement
Four detent grooves provide a secure connection with the retaining ball of a drive tool. Radiused corners reinforce the drive end by eliminating sharp angles that are prone to cracking under stress. The drive end's beveled edge helps guide a ratchet tang smoothly onto the socket.
Twist-to-Lock Socket Rail
The patented twist-to-lock rail system organizes and securely holds sockets in place—both for in your toolbox and on the go. A quick twist of the socket locks it onto the rail so that it can't fall off.
