  • Item Features
  • Application
  • 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
