Robertson Square Drive Screwdriver #1 Head / Green Handle

Original Robertson® No.1 scrulox / screwlux / square drive screwdriver.

GREEN HANDLE - the colour indicates the size, so you can quickly identify the driver you need from the rest of the tools in your toolbox.

This screwdriver suits screw gauges 5, 6 and 7 (less common, smaller sizes).

Robertson screwdrivers are easy to use one-handed, because the tapered square head tends to retain the screw, even if it is shaken.
