The hex head design of these screws allows them to be installed using a torque wrench or wrench. The self-drilling feature of these screws means they drill themselves as the screws are driven in, eliminating the need for pre-drilling.
This kind of screw is usually used to fix metal components, such as metal roofs, metal wall panels, etc. If you need more information about the specifications, sizes or applicable scenarios of this screw, please feel free to let me know.
