A hexagonal flat head tapping screw as defined by DIN 571 is a self-tapping screw with a hexagonal head and drilled end. These screws are designed to self-tap threads in materials without the need for pre-drilling or tapping, and are suitable for use in a wide range of materials such as wood, metal and plastic.
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-Tapping Capability: The drill-tail design eliminates the need to pre-drill or tap screws, allowing them to be drilled and threaded directly into the material, simplifying construction steps. Hexagonal Head: Provides a wide bearing surface that makes tightening and loosening operations easier and can withstand higher torque. Flat head design: The flat design of the head allows the screw to be installed flush with the surface of the material, providing a neat appearance. CORROSION RESISTANCE: The screws are usually zinc plated or other surface treatments, which enhances their corrosion resistance and makes them suitable for outdoor or wet environments.
Scope of Application
Carpentry and Furniture Making: for carpentry projects and furniture assembly, providing a solid connection while maintaining a neat appearance. Construction and Renovation: for fixing plasterboard, wood panels and other decorative materials in construction and renovation projects. Machinery and equipment assembly: for fixing machine parts or structural components in machine building and equipment assembly. Electronic and electrical equipment: in the assembly of housings and components for electronic equipment, to provide stable and aesthetically pleasing connections.
