Customized Round Head Stainless/Carbon Steel Self Tapping Screw for Black Drywall/Wood/Machine/Chipboard/Roofing/Metal/Furniture/Gypsum Drilling

Product Description

Product Description
The external hexagonal drill tail self tapping screw is a type of mechanical screw with a hexagonal head and a special drill function at the tail, which can be drilled into the material during installation to form a more secure connection. This design makes the hexagonal drill tail self tapping screw widely used in multiple fields.
The characteristics of the hexagonal drill tail self tapping screw mainly include the following aspects:
Strong corrosion resistance: Some external hexagonal drill tail self tapping screws adopt surface treatment technologies such as galvanizing or chrome plating, which improves the anti rust ability of the screws, extends their service life, and enables them to maintain good performance in different environments.
Easy installation: The hexagonal design allows the tool to firmly grip the screw, facilitating rotation operations and greatly simplifying the installation process. In addition, the drill tail design allows screws to be directly drilled into the material and fixed without the need for pre drilling.
High strength and durability: The hexagonal shape gives the screw greater torque, which can better maintain the firmness of the connection and is suitable for various types of materials such as wood, plastic, metal, etc. Its high strength and toughness enable it to withstand greater tensile and compressive forces, making it more reliable during the fastening process.
Diversified specifications and tail design: The specifications of the external hexagonal drill tail self tapping screw are diverse, including different diameters, lengths, and thread lengths, to meet the fastening needs in different scenarios. There are also various options for tail design, such as countersunk, cross, millet, plum blossom, and round head shapes.
Good anti-theft performance: Due to its special structure and tightening method, the hexagonal drill tail self tapping screw has a certain anti-theft performance, which can effectively prevent illegal disassembly.
Application scenario: Hexagonal drill tail self tapping screws are widely used in the construction and furniture manufacturing industries. In the field of architecture, they are commonly used for fixed connections such as bridges, stairs, doors and windows, and are particularly suitable for humid environments such as bathrooms and kitchens. In furniture manufacturing, they provide good fixing performance for furniture. In addition, due to their efficient and fast installation characteristics, they are also widely used in automotive manufacturing and other industrial fields that require rapid assembly.
