Plum semi-countersunk head self-tapping nails defined by GB2670.3 are a type of self-tapping screw characterized by their hexagonal socket and semi-countersunk head. These screws are designed to create their own threads as they are driven into materials, eliminating the need for pre-drilled holes.

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 connection without pre-drilling.

Hexagonal Socket: The hexagonal drive allows for better torque transfer and reduces the risk of slipping during installation.

Countersunk Head: The design allows the screw to sit flush with the surface, providing a smooth and clean finish, which is ideal for aesthetic applications.

Corrosion Resistance: Often coated with protective finishes, these screws are resistant to rust and corrosion, making them suitable for various environments.

Versatility: Available in various sizes and thread pitches, these screws can be used in a wide range of applications, including furniture assembly and construction projects.

Scope of Application

Furniture Assembly: Ideal for assembling wooden furniture where a strong and secure connection is required, and a clean appearance is desired.

Woodworking Projects: Perfect for projects that require a flush finish, such as cabinetry and decorative woodwork.

Construction: Used in securing wooden components, such as joists and beams, where a countersunk finish is preferred.

Renovation and Repair: Effective for reinforcing existing wooden structures 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.
