1/2 Inch Drive Shallow External Star Socket Set with Rail, 10-Piece (E8 - E24)

• External Star Geometry – Shallow 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 chrome-plated exterior is highly corrosion-resistant and wipes clean to a mirror finish, and the interior chrome plating is supplemented with a clear coat or painted finish where needed for full coverage • 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
The shallow external star sockets are a female 6-lobe geometry designed for a high-torque fit that resists slipping. These sockets are required for E-Star fasteners, which are commonly found on seat mounts, brake system components, and steering columns.
