Proto® Tether-Ready 3/8" Drive Metric Hex Bit Sockets
Discontinued J4990-10M-TT
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.
Additional Features
- Made using a heat treated alloy for wear-resistance which helps minimize distortion for a long life.
