Stainless Steel Flat tail self tapping screw Manufacturers

How does the Flat tail self tapping screw perform differently when connecting wood, plastic, and metal sheets? ​

Wood connection: Advantages of grip and applicability ​
Wood is a very common application material for Flat tail self tapping screws. Its loose and porous characteristics are well matched with the structure of Flat tail self tapping screws. Wood is mainly composed of cellulose, hemicellulose, and lignin. In terms of mechanical properties, wood has high tensile strength along the fiber direction, but relatively weak lateral compressive strength. The Flat tail self tapping screws manufactured by Zhongke Metal Technology have sharp threads and moderate hardness after a special heat treatment process. When screwed into the wood, the screw can cut the wood fibers with its sharp threads, forming a tightly fitting threaded hole inside the wood, and the two bite each other to produce a strong grip. ​
From the perspective of wood types, soft wood such as pine has a large cell cavity and soft material. Flat tail self tapping screws require less torque when screwed in, and can be installed quickly, greatly improving construction efficiency. In the field of furniture manufacturing, the use of flat-tail self-tapping screws to connect pine wood parts is not only convenient for assembly, but also able to withstand external forces such as pushing, pulling, and load-bearing in daily use, and maintain the stability of the furniture structure. Hard wood such as oak has a tight cell structure and is hard and dense. The flat-tail self-tapping screws produced by Zhongke Metal Technology, with good strength and toughness, can be smoothly penetrated even in the face of the resistance of hard wood to form a solid connection. In wooden structures, flat-tail self-tapping screws connect hard wood closely to build a solid frame to resist wind and rain erosion and daily wear and tear, ensuring the long-term safety and stability of the building. ​
Plastic connection: the key role of precise adaptation and protection ​
Plastic materials have significant differences in properties from wood. They are soft and have certain elasticity and brittleness. There are many types of plastics, and the molecular structures and physical properties of different plastics are different. Taking polypropylene as an example, it has good chemical corrosion resistance and certain flexibility, but low hardness; polyvinyl chloride has a higher hardness and good flame retardancy and weather resistance. Flat-tail self-tapping screws are designed to precisely control the pitch, tooth shape and tip angle of the thread. When screwed into plastic materials, this carefully designed screw can form a suitable threaded hole inside the plastic with minimal cutting force, avoiding excessive extrusion and damage to the plastic. ​
In actual applications, for plastics with lower hardness, although it is relatively easy to screw in flat-tail self-tapping screws, if the screwing torque is too large, it is very easy to cause deformation or cracking of plastic parts. Zhongke Metal Technology undergoes strict torque testing for each batch of products to ensure that the torque of the screws is stable during use, effectively avoiding such problems. In the assembly of plastic products, such as plastic storage boxes and plastic toys, flat-tail self-tapping screws can reliably connect the components while protecting the integrity of the plastic materials, making the product beautiful in appearance and tightly connected. For engineering plastics with higher hardness, flat-tail self-tapping screws can still achieve stable connection with reasonable structural design and good mechanical properties. In the plastic pipe fixing scenario, flat-tail self-tapping screws firmly connect the pipe to the bracket, ensuring that the pipe system will not loosen due to vibration, pressure and other factors during long-term use, and ensuring the sealing and normal operation of the pipe system.​
Metal sheet connection: guarantee of high strength and stability​
Metal sheet connection places extremely high demands on the strength and precision of flat-tail self-tapping screws. Metal sheets are usually thin, generally between 0.5 and 3 mm, and their strength and rigidity are relatively weak, which makes them prone to deformation and tearing during the connection process. Each batch of high-strength flat-tail self-tapping screws we produce is tested for tapping speed to ensure product accuracy and stability. The screws are made of high-quality metal materials and have high strength and good toughness through advanced manufacturing processes. When connecting metal sheets, the screws can tap high-quality internal threads on the sheets with precise thread design to achieve tight engagement. ​
The flat tail design of flat-tail self-tapping screws plays an important role in metal sheet connection. The flat tail increases the contact area with the metal sheet, effectively disperses stress when subjected to force, and prevents the metal sheet from deforming or tearing due to local stress concentration. In the automotive manufacturing industry, a large number of metal sheet components are used in the car body, which need to withstand vibration, impact and complex mechanical environment during driving. With stable and reliable connection performance, the various parts of the car body are tightly combined to ensure the strength and rigidity of the car body structure, and improve the safety and durability of the car. In the field of electrical housing assembly, the electrical housing made of metal sheets needs to have good sealing and protection. Flat-tail self-tapping screws are tightly connected to ensure the integrity of the housing, prevent dust and water vapor from intruding, and protect the normal operation of the internal components of the electrical appliance.
