Square Drive Screws

1907 Robertson Advert

Advert for Robertson square drive screws from 1907

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

There is no doubt that this type of screw is so user friendly that once used, you will probably never go back to a conventional type. The screw head has a deep square recess to take the driver. The driver locks into the screw head so that you can wave it about and the screw will not fall off.

We keep screwdrivers to match the screws.
