Product Description

The Hexagonal Huasi Drill Tail Screw is a remarkable fastener, expertly crafted to provide seamless installation coupled with robust fastening capabilities. Its unique design and broad application scenarios are elaborated as follows:

1. Structural characteristics

1. Hexagonal head design

Tool adaptability: Featuring a standardized hexagonal design, this head perfectly partners with wrenches and power tools, ensuring stable torque transmission that prevents slippage during installation.

High torque bearing capacity: The hexagonal design masterfully disperses rotational stress, making it ideal for high-strength fastening needs, thereby guaranteeing dependable connections.

2. Huasi (spring washer) integration

Anti-loosening mechanism: Through elastic deformation, Huasi delivers pre-tightening force, combating loosening from vibrations or impacts, making it especially valuable in dynamic load environments.

Surface protection: Select models undergo galvanizing or Dacromet treatments, enhancing their corrosion resistance and significantly prolonging their lifespan.

3. Drill tail self-attack functionality

• Installation without pre-drilling: The tail mimics a drill point or Fried Dough Twists bit, effortlessly drilling, tapping, and locking onto metal plates (up to 6mm), wood, plastic, and more, streamlining construction processes.

• High bite force thread: With optimized self-tapping threads, this design swiftly penetrates materials to form a mechanical bite, boosting connection strength substantially.

2. Performance advantages

1. Enhancement of construction efficiency

Single process completion: By integrating drilling, tapping, and locking functions, efficiency surges by over 50% compared to traditional bolt installations, making it perfect for large-scale projects.

Tool compatibility: Its versatility with manual or electric tools minimizes the skill level required for operation.

2. Improved connection stability

Multi-level anti-loosening design: Combining hexagonal head torque control, Huasi elastic compensation, and drill tail thread engagement, it forms a triple anti-loosening system, far surpassing ordinary screw vibration resistance.

Wide material adaptability: Capable of penetrating thin-walled materials like color steel plates, galvanized plates, and aluminum alloys without damaging surface coatings.

3. Environmental tolerance

Material selection: Constructed from premium carbon steel (e.g., 1022A), stainless steel (304/410), or alloy steel, these screws meet diverse corrosion resistance needs.

Surface treatment: Featuring processes such as white zinc plating, color zinc plating, and black phosphating, these screws thrive in harsh environments like humidity and salt spray.

3. Typical application scenarios

1. Building steel structure

Color steel tile fixation: Ideal for securing color steel plates and keels on roofs and walls, the drill tail design precludes water leakage risks associated with pre-drilling.

Light steel keel assembly: Efficiently fastens keel nodes in partition and ceiling systems, accelerating construction timelines.

2. Manufacturing of mechanical equipment

Thin plate assembly: Perfect for connecting side panels and frames of chassis and cabinets, it decreases drilling requirements and reduces costs.

Vibration equipment fastening: With Huasi anti-loosening functionality, it's ideal for motor bases, fan brackets, and more, ensuring long-term stability even in vibrational contexts.
