- 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
- Proto® bits are offered in a broad range to accommodate production assembly applications
