Made from Cr-V Steel The chromium-vanadium socket is heat-treated to 40.547.5 HRC for use on impact wrenches
Corrosion-Resistant The socket is coated with a manganese phosphate finish to resist corrosion
Two Size Markings The size is marked with a high-visibility laser marking and a permanent stamped marking that won’t rub off
Friction Ring or Detent Pin Anvils Smooth walls inside the drive end and a detent pin hole make the bit sockets compatible with both drive tool anvil types
Tekton’s shallow impact external star (E-Star) sockets are made from 6140 chromium vanadium steel that’s heat-treated to 40.547.5 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.
