Square-Drive Screws

How many stripped screws have people endured. Or how many times have we tried to keep the driver in the center of the slot. Many of us have, for years, resorted to using the screw as a nail for the last 1/2 inch when it has been stripped out. This is one of those "why don't we use it more" ideas. The square-drive and screws also known as the Robertson Screw.

The square drive doesn't let the drive slip off the head of the screw and since it is a simple square hole it doesn't strip very easily if ever. It is a simple, solid design with only one problem, it is so strong that it can be screwed too tight. 

The square drive was actually invented in 1908, nearly thirty years before the Philips head, and was an American standard at the time. (the model T used these screws) 

Like many great designs. the square drive is no longer the standard due to poor business practices by the original inventor that allowed the Philips and other options to gain traction. But this screw is still used heavily in construction and woodwork for its tough, reliable characteristics.

The Robertson screw is really a testament to the idea of making something that lasts. The screw is tough. It gives off this idea from the shape on its head. It isn't a smooth, curving, beautiful thing. It was meant to get stuff done where nothing else worked.
