Cross countersunk self-tapping nails with flat tail cutting, also known as flat head self-tapping screws with a flat end and a cutting thread, are a type of self-tapping screw that is designed to create its own thread in the material being fastened. The flat tail cutting feature refers to the end of the screw's shank, which is flat and designed to cut through materials for a secure grip.
Stainless Steel (304/316): Offers superior corrosion resistance and is suitable for moist or corrosive environments. The 316 grade has additional molybdenum, providing even better corrosion resistance, especially in marine applications.
Carbon Steel: Provides good strength and is the most common material for bolts. It may require additional surface treatments like galvanizing for increased corrosion resistance.
Alloy Steel: Offers enhanced strength and durability. It is often used in high-stress applications where high tensile strength is required.
Advantage:
Flush Finish: The countersunk head design allows the screw to sit below the surface of the material, providing a professional and smooth finish that is ideal for applications where aesthetics are important.
Self-Tapping Capability: These screws have a cutting thread that enables them to tap their own threads without the need for pre-drilling or tapping, which can save time and effort.
Strong Grip: The flat tail cutting end ensures a strong grip on the material, making these screws suitable for heavy-duty applications.
Scope of Application
Automotive and Marine Applications: Due to their corrosion resistance, these screws are often used in automotive and marine applications where components need to be securely fastened and withstand harsh environments.
Woodworking and Furniture Making: In woodworking, these screws are used for joining wooden parts where a flush surface finish is desired, such as in the construction of furniture, cabinetry, and wooden structures.
Metal and Plastic Assemblies: The flat tail cutting screws can be used in the assembly of metal and plastic parts where a strong and secure fastening is required.
