Self Drilling Screws
Self-drilling screws can be identified by the drill bit shaped point of the screw and are designed for a variety of applications such as fastening metal to metal and metal to wood. Self-drilling screws do not require a pilot hole, which accelerates installation time and lowers the cost and need of additional drill bits. This extra functionality and cost saving feature makes self-drilling screws the clear choice for metal building construction. The drill points are numbers #1 through #5 and the amount of steel they can drill through increases as the numbered point increases. Typically, self-drilling screws are used in light gauge applications but a #5 drill point can drill through and fasten up 1/2" of steel. During installation, self-drilling screws will also tap threads to a degree.
