A hex head self-drilling screw is a type of screw that incorporates a hexagonal head, allowing it to be driven with a wrench or socket, offering greater torque and stability during installation. The self-drilling feature means that the screw has a unique point design that allows it to drill its own pilot hole in materials like metal, wood, and plastic without the need for pre-drilling. This eliminates the need for additional tools and saves time, making it an efficient choice for various applications.
