  • Proto® Tethered Tool Sockets are manufactured with four detent holes so that the pin detent will engage correctly regardless of the direction the socket is placed on the square drive.
  • The Positive Control System requires a separate tool to attach or remove the socket, meaning it cannot be removed without specific intent.
  • Chrome finish is applied after the holes are bored for better corrosion resistance.
  • Made using a heat treated alloy for wear-resistance which helps minimize distortion for a long life.
  • Hex opening holds the bit allowing the bit holder to take the torque load.
