Robertson is famous for the patent of the socket-head screw, widely known today as the square recess. The Robertson system perfectly mates the taper drive bit tip to the square recess punched in the screw. The result is a very precise fit: no cam-out, no slippage in the drive. The drive style manufactured today is known as Recex – a combination of Phillips and Robertson drives, allowing convenient use of either drive type. Often considered the woodworker’s screw of choice, Robertson screws are commonly used by furniture manufacturers, cabinetmakers and tradespeople.
Suitable for use in plywood, particleboard, medium-density fiberboard and softwood, these screws are also appropriate for some hardwoods, such as oak and maple. They are heat treated for hardness and lubricated, and the angle and depth of the thread provide excellent holding capability. Available in pan or flat head.
