Square Socket

Square Socket Recess

In 1908, Robertson-Whitehouse invented the square drive screw. This was the first recess drive type fastener practical for production usage. Still known today as the Robertson Drive, its Square recess reduces slippage and prevents damage to both the screw and surrounding material due to cam-out of the driver bit.
