TEKTON 3/8-in Drive E18 External torx Bit Driver Socket

External Star Geometry – External star (E-Star) sockets have an internal 6-lobe geometry designed for a high-torque fit that resists slipping

Materials – The socket is made from 50BV30 steel and hardened to 40–47 HRC for strength and durability

Exterior and Interior Finishes – The socket is protected against corrosion with chrome plating on the outside and clear coat on the inside

Large, Stamped Markings – Permanently impressed into the material by a roll-stamp die and as large as possible while still being readable along the socket's curved surface

Secure Drive Tool Engagement – Detent grooves and beveled edges provide a smooth and secure connection with the drive tool
