Hex washer slot concrete screws have a six sided hexagonal head to allow for secure driving. They are designed to cut their own thread into concrete or brick. Their design eliminates the need for a secondary anchor. The hex washer slot design is used for easy installation and removal and for when the application does not require a flush seating of the screw.
