Self-drilling screw is an innovative screw design with a drill tail or pointed tail shape at the end, which does not require auxiliary processing. It can be directly drilled, tapped, and locked on the setting material and base material, thereby greatly saving construction time. The design principle of this type of screw is based on the physical and mathematical principles of the object's inclined circular rotation and friction force. It is a type of screw that gradually tightens the object's components. Drill tail screws have a wide range of applications, mainly used for fixing color steel tiles in steel structures, and can also be used for fixing thin sheet materials in simple buildings. Although it is convenient to use and can be directly applied to materials by drilling the wire into the base material and lightly tapping to lock it, saving a lot of construction time, it cannot be used for metal to metal bonding and fixation.
There are various specifications and sizes of drill tail screws, commonly including hexagonal drill tail screws and countersunk drill tail screws. Self-drilling screw have a length of about 20-25mm and a diameter of 5.5mm, while countersunk drill tail screws have a length of about 13-60mm and a diameter of about 3.8mm. There are also various materials for drill tail screws, including carbon steel, stainless steel, stainless steel, and composite materials. Users can choose according to their specific usage needs and budget. Carbon steel drill tail wire has low cost but is prone to rusting, stainless steel drill tail wire has good rust prevention performance but high cost, while stainless steel provides good rust prevention ability and certain cost-effectiveness.
Overall, due to its fast automatic drilling, high construction efficiency, high bonding force, high pre tightening force, and high stability, drill tail screws perform well in the combination of buildings, residences, and other places, and are an economical type of fastener. Especially in the construction of high-rise buildings and high-speed transportation, the demand for high-quality drilling screws is more urgent.
Standards and specifications for self-drilling screw
There are various specifications and sizes of self-drilling screw, commonly including hexagonal drill tail wire and countersunk drill tail wire. The specification of hexagonal drill tail wire is about 20-25mm in length and 5.5mm in diameter; The specification of the countersunk drill tail wire is about 13-60mm in length and 3.8mm in diameter.
Classification of Self-drilling screw
Self-drilling screw can be divided according to the shape of the drill tail, commonly including round headed millet, cross, plum blossom, hexagonal sliding wire, round headed sliding wire, horn head, etc. In addition, according to the different materials, drill tail wires can be divided into types such as carbon steel, stainless steel, stainless steel, and composite materials.
The main characteristics of Self-drilling screw include drilling, tapping, and locking completed in one go, strong bonding force, saving construction time, improving work efficiency, professional manufacturing, and quality assurance. These characteristics make drill tail screws widely used in various fields.
Drilling, tapping, and locking can be completed in one go: The design of the drill tail screw allows for the simultaneous completion of drilling, tapping, and locking during the installation process, which not only simplifies the installation process but also enhances installation efficiency.
Strong bonding force: Due to its special structural design, the drill tail screw can provide strong bonding force, ensuring the stability of installation.
Save construction time and improve work efficiency: Due to the simplified installation process, Self-drilling screw can significantly reduce construction time and improve work efficiency.
Professional manufacturing, quality assurance:Self-drilling screw are usually produced by professional manufacturers, ensuring the stability of product quality and performance.
The characteristics of Self-drilling screw make them widely used in engineering installations such as stainless steel plates, metal steel plates, galvanized steel plates, as well as indoor and outdoor installations such as metal curtain walls, metal light partitions, plastic steel doors and windows. In addition, it is also suitable for the combined installation of general angle steel, channel steel, iron plate and other metal materials, as well as assembly projects such as automobile carriages, container boxes, shipbuilding, refrigeration equipment, environmental engineering, etc.
The use of Self-drilling screw is very extensive, mainly used to fix and connect various materials, including wood, metal, gypsum board, etc.
Self-drilling screw have been widely used in various fields due to their unique structure and function. The following are the main uses of drill tail screws:
1.Wood fixation: Used on wooden items such as furniture, wooden flooring, etc. They have a sturdy structure and self tapping threads that can easily penetrate wood and provide reliable connections.
2.Metal material fixation: Especially suitable for metal materials such as aluminum alloy, steel, etc. Its hard tip and high-strength threads can pierce through metal surfaces and provide reliable fastening effect.
3.Gypsum board and drywall fixing: specifically used for fixing on dry materials such as gypsum board and drywall. They usually have sharp self tapping threads that can directly drill into the material during installation, providing a secure fixation effect.
4.Waterproof function: In the field of construction, especially in wooden structures, drill tail screws are not only used for connection and fastening, but also have waterproof function, improving their service life in water related environments.
The design of the tail screw allows it to directly drill into the material during installation, eliminating the need for pre drilling and greatly saving construction time. In addition, the tail design of the drill tail screw comes in various shapes, such as countersunk, cross, meter shaped, plum blossom, etc., to meet different installation requirements. These characteristics make drilling screws an indispensable fixing material in fields such as home decoration and construction.
