Hexagonal Huasi pointed cutting tail screw is a fastener that combines efficient installation and reliable fastening performance. Its core design features, performance advantages, and application scenarios are as follows:
1, Structural features
1. Hexagonal head design
Tool adaptability: The head adopts a standard hexagonal shape, which is compatible with wrenches or power tools, providing stable torque transmission, avoiding slippage during installation, and ensuring precise and efficient operation.
Mechanical stability: Hexagonal structure disperses stress, enhances torsional performance, suitable for high-strength fastening scenarios, and improves connection reliability.
2. Huasi (spring washer) integration
Dynamic anti loosening: Huasi compensates for looseness caused by vibration or impact through elastic deformation, especially suitable for dynamic load environments, ensuring connection stability.
Material compatibility: High strength stainless steel or carbon steel is usually used, with surface galvanized or treated with Dacromet to improve corrosion resistance and extend service life.
3. Sharp cut tail (drill tail) design
• Self tapping and self drilling function: the tail is in the shape of a drill point or Fried Dough Twists, which can directly penetrate metal plate (thickness ≤ 6mm), wood, plastic and other materials without pre drilling, simplifying the construction process.
• High bite force thread: The thread design is optimized for self tapping type, which quickly cuts into the material and forms a mechanical bite, enhancing the connection strength, especially suitable for thin plate connections.
2, Performance advantages
1. Improvement of construction efficiency
Single process installation: Integrated drilling, tapping, and locking functions, with an efficiency increase of over 50% compared to traditional bolt installation, suitable for large-scale projects.
Tool compatibility: Suitable for manual or electric tools, reducing the skill requirements for operators and improving construction flexibility.
2. Enhanced connection stability
Multi level anti loosening system: Hexagonal head torque control+Huasi elastic compensation+drilling tail thread engagement, forming a triple anti loosening mechanism, with better anti vibration performance than ordinary screws.
High load-bearing capacity: suitable for medium to high strength load scenarios, such as steel structure connections, mechanical assembly, etc., ensuring safe and reliable connections.
3. Environmental adaptability
Corrosion resistance: Made of stainless steel (such as 304, 316) or galvanized carbon steel, suitable for harsh environments such as humidity and salt spray.
Wear resistance: The combination of high-strength materials and surface treatment processes enhances wear resistance and extends service life.
3, Typical application scenarios
1. Building steel hook
2. Manufacturing of mechanical equipment
3. Cars and Transportation Vehicles
4. Electronics and Home Appliances Industry
Four selection criteria
Material thickness: Drill tail screws are suitable for single-layer metal plates with a thickness of ≤ 6mm. If this range is exceeded, pre drilling is required.
• Load type: In dynamic load scenarios (such as vibration equipment), stainless steel material+Huasi structure is preferred; Carbon steel galvanized version is available for static load scenarios.
