3/8″ Drive Hex Bits Sockets – J4990-6M-TT

> 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.
