Professional manufacturer of one-stop supporting products for industrial and mining accessories.
Structural Characteristics
Head Shape: The head is round, with a smooth and aesthetically pleasing appearance. Compared to hexagon head self-tapping screws, the round head can reduce scratching and damage to the installation surface in certain situations, especially suitable for applications with high surface requirements or where sharp edges need to be avoided.
Drill Tail Section: Like hexagon head self-tapping screws, the drill tail has a sharp drill bit structure with cutting edges and chip removal grooves, allowing it to drill and tap into materials without the need for pre-drilling and tapping operations, effectively improving installation efficiency.
Thread Section: Typically uses self-tapping coarse threads, which allow the screw to quickly form a reliable threaded connection when penetrating the material, providing good self-locking performance to effectively prevent loosening and ensure the strength of the connection.
Material
Carbon Steel: Commonly used for round head self-tapping screws due to its good strength and economy. After surface treatments such as galvanizing and nickel plating, its corrosion resistance and wear resistance can be enhanced, making it suitable for connections in general construction, furniture, and other fields.
Stainless Steel: Exhibits excellent corrosion resistance, maintaining good performance in harsh environments such as humidity and acidic or alkaline conditions. It is commonly used in outdoor construction, marine engineering, food processing equipment, and other applications with high corrosion resistance requirements, with common types including 304 and 316 stainless steel.
Aluminum Alloy: Lightweight, corrosion-resistant, and with certain strength, suitable for fields with strict weight requirements such as aerospace and electronic devices. Additionally, round head self-tapping screws made of aluminum alloy also have a certain aesthetic appeal.
Specifications and Models
Classified by size specifications: Common diameter specifications include M3, M4, M5, M6, M8, etc., with lengths ranging from a few millimeters to several tens of millimeters to meet the connection needs of materials of different thicknesses. Suitable specifications can be selected based on specific application scenarios.
Classified by thread type: Mainly divided into coarse threads and fine threads. Coarse threads can quickly penetrate the material during connection, providing greater connection strength, suitable for general fastening connections; fine threads offer higher precision and better anti-loosening performance, suitable for applications requiring high connection accuracy and reliability.
Application Fields
Building Decoration: Widely used in the field of building decoration, such as fixing decorative panels, ceilings, curtain walls, etc. The round head design can avoid damaging the surface of decorative materials during installation, ensuring the aesthetic effect of the decoration.
Furniture Manufacturing: Commonly used in furniture assembly, such as connecting wooden boards and metal frames. Its self-drilling and self-tapping characteristics can simplify the installation process and improve production efficiency, while the round head appearance is more harmonious with the overall design of the furniture.
Electronics and Electrical Appliances: Plays an important role in the installation of electronic device enclosures and fixing circuit boards. Due to its rounded head, it will not scratch electronic components or device enclosures, effectively protecting the appearance and internal components of the equipment.
Automotive Interior: Suitable for fixing automotive interior parts, such as the installation of seats, dashboards, and door trim panels. Round head self-tapping screws can achieve a firm connection without damaging the surface of the interior materials, while their good anti-loosening performance can ensure the stability of interior parts during vehicle operation.
