Key Features
Precise E-Star Geometry
The internal six-lobe geometry provides a high-torque fit that resists slipping and fastener rounding under impact loads.
Impact Rated
Heat-treated to 40–47 HRC, this socket is built for repeated use with impact wrenches, not just hand tools.
Friction Ring or Detent Pin Compatibility
Smooth drive-end walls support friction ring anvils while a detent pin hole supports detent pin anvil styles — works with both drive tool types.
Permanent Size Markings
Laser-etched and stamped markings stay readable for the life of the socket.
Use Cases and Best-Fit Shopper
Mechanics and DIYers removing external Torx-style bolts on alternators, thermostats, and engine components with an impact wrench.
