TEKTON 1/2 in. Drive External Star Impact Socket Set (9-Piece) (E10-E24)

Tekton's shallow impact external star (E-Star) sockets are made from 6140 chromium vanadium steel that's heat-treated to 40.5-47.5 HRC for use on impact wrenches. The socket is coated with a manganese phosphate finish to resist corrosion and has both a high-visibility laser size marking and a permanent stamped size marking. The inside of the socket's drive end has smooth walls with no detent grooves to support engagement with drive tools that use friction ring anvils. A detent pin hole on one side of the drive end also supports engagement with detent pin anvil styles. This set includes a portable organization rail.
