Robertson Screwdriver Black #3 Square Drive Head

Original Robertson® No.3 scrulox / screwlux / square drive screwdriver.

BLACK 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 12 and 14 (larger type).

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