Flat Head Drill Tail Screws, also known as Flat Head Self Drilling Screws, are self-tapping screws with a special design that has a flat head and a drill or pointed tail. This design allows the screw to be drilled, tapped, and locked directly into the target material, resulting in significant savings in construction time and increased work efficiency.
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:
Self-drilling function: The flat head drill wire's tail design allows it to be drilled directly into the material without pre-drilling, reducing the number of construction steps.
Flat head design: The flat design of the head allows the screw to be flush with the surface of the material after installation, which is suitable for applications where a flat surface is required or where aesthetics are of high importance.
High strength: usually made of high strength steel, such as 1022A carbon steel, after heat treatment, the surface hardness can be up to HV560-750, the heart hardness HV240-450, to ensure that the screws are tough and durable.
Corrosion resistance: Surface treatments such as zinc plating can provide additional protection to prevent screws from rusting, suitable for outdoor or humid environments.
Scope of Application
Automotive Restoration: Used for bodywork where a flush, seamless finish is essential.
Fine Woodworking: Employed in projects that require a clean, countersunk appearance without the need for additional sanding or filling.
Metalworking: Perfect for attaching metal sheets or components where a flush mount is preferred.
