Square Drive Screws

Square drive screws and matching Robertson scrulox screwdrivers.

Square drive screws were invented by Canadian Peter L. Robertson over 110 years ago in 1908

The screw head has a deep square recess to take the driver. The screwdriver locks into the screw head so that you can wave it about and the screw will not fall off.
