DIN7504k steel yellow zinc hex flange head self-drilling screws are a type of fastener commonly used in construction and metalworking applications. These screws have a hexagonal flange head, which provides a larger surface area for better grip and distribution of force. The yellow zinc coating on the steel helps to protect the screw from corrosion and provides an attractive finish.The self-drilling feature of these screws means that they have a drill bit-like point, allowing them to drill their own pilot hole as they are driven into the material. This eliminates the need for pre-drilling and makes installation faster and more efficient.These self-drilling screws are commonly used in metal-to-metal applications, such as attaching metal roofing sheets or metal siding to a structure. They are also used in wood-to-metal applications, where they can drill through the wood and securely fasten it to a metal frame or support.self drilling screw wood self drilling screw for wood Overall, DIN750…
