What type of screwdriver is square-shaped at the head?

  1. Phillips screwdriver

  2. Flathead screwdriver

  3. Robertson screwdriver

  4. Hex screwdriver

The correct answer is: Robertson screwdriver

The Robertson screwdriver is recognized for its square-shaped head, allowing for better engagement with the corresponding square socket in the screw. This design enhances torque and grip, reducing the likelihood of slippage during use. It was invented by Canadian engineer Peter L. Robertson and has become particularly favored in woodworking and construction applications due to its ability to maintain contact with the screw, even at awkward angles. The square shape not only provides a secure fit but also helps in preventing the driver from falling out of the screw, which is a common issue with other types of screwdrivers.
