Proto® Tether-Ready 3/8" Drive Metric Hex Bit Sockets

  • 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
