Plum large flat head self-tapping nails, which are defined by GB2670.1, are a type of self-tapping screw with a hexalobular (or Torx) drive and a large flat head, often countersunk. These screws are designed to be driven into materials to create their own threads, eliminating the need for pre-drilled holes or tapping. The GB2670.1 standard specifies the characteristics of these screws, including dimensions, thread sizes, and material properties.
Carbon Steel: Typically used for general applications.
Stainless Steel: For environments where corrosion resistance is required.
Alloy Steels: Used in applications requiring high strength or high temperature resistance.
Advantage:
Self-Tapping Capability: These screws can create their own threads in materials like wood, metal, and plastic, providing a secure and flush connection without the need for pre-drilled holes.
Hexalobular Drive: The hexalobular (Torx) drive provides a high torque transfer and reduces the risk of the tool slipping during installation, which is particularly useful in power tool applications.
Self-Cutting Threads: These screws can cut their own threads in the material, eliminating the need for pre-drilling or tapping, which saves time and effort.
High and Low Tooth Design: The thread design with alternating high and low teeth provides better grip and allows the screw to penetrate harder materials more effectively.
Hexagon Head: The hexagonal head allows for use with a wrench or a driver, providing a better grip and reducing the risk of the tool slipping during installation.
Scope of Application
Construction: Used in construction projects for securing wooden components, such as joists, beams, and panels, where a countersunk finish is preferred.
Renovation and Repair: Effective for renovation and repair work where existing wooden structures need to be reinforced or secured with a flush connection.
Machinery and Equipment: Used in the assembly of wooden parts in machinery and equipment where a strong and reliable fastening solution is needed.
