A Robertson screw, also known as a square screw drive, is a type of screw drive that is characterized by a square-shaped recess in the head of the screw. The screw drive is designed to be used with a square driver, rather than a traditional slotted or Phillips driver, and is known for its strong grip and resistance to cam-out, which is when a screwdriver slips out of the screw head while turning it.
Robertson screws are commonly used in woodworking and cabinetry, as well as in the manufacture of furniture and other household items. They are also used in a variety of other applications, including electrical and plumbing work, as well as in the automotive and aerospace industries. The screw’s square shape provides a larger surface area for the driver to grip, which can help to prevent slipping and increase torque, making it a popular choice for applications where a secure, high-torque connection is required. Robertson screwdrivers are easy to use one-handed because the tapered socket tends to retain the screw, even if it is shaken.
