Product Description

The Hexagonal Huasi Drill Tail Screw is an innovative fastener that seamlessly combines ease of installation with high-strength securing capabilities. Its core design features and typical application scenarios are detailed below:

1. Structural Characteristics

1. Hexagonal Head Design

Tool Adaptability: Crafted with a standard hexagonal head, this design is perfectly suited for use with wrenches or power tools, ensuring stable torque transmission and minimizing slippage during installation.

High Torque Bearing Capacity: The robust hexagonal structure effectively distributes rotational stress, making it ideal for high-strength fastening applications and guaranteeing reliable connections.

2. Huasi (Spring Washer) Integration

Anti-Loosening Mechanism: The Huasi component provides a pre-tightening force through elastic deformation, effectively counteracting loosening from vibration or impact, making it especially suitable for dynamic load environments.

Surface Protection: Select models undergo galvanizing or Dacromet treatment, significantly enhancing corrosion resistance and prolonging the service life of the screw.

3. Drill Tail Self-Attack Function

• Installation Without Pre-Drilling: Featuring a tail akin to a drill point or Fried Dough Twists drill bit, it can directly drill, tap, and lock onto metal plates (thickness ≤ 6mm), wood, plastic, and more, thus simplifying the construction process.

• High Bite Force Thread: The optimized thread design for self-tapping ensures quick penetration into the material, forming a secure mechanical bite and enhancing connection strength.

2. Performance Advantages

1. Improvement of Construction Efficiency

Single Process Completion: Boasting integrated drilling, tapping, and locking functions, it increases efficiency by over 50% compared to traditional bolt installation, making it ideal for large-scale projects.

Tool Compatibility: Engineered for both manual and electric tools, it reduces the skill level required from operators, facilitating smoother operations.

2. Enhanced 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, offering superior anti-vibration performance over ordinary screws.

Wide Material Adaptability: Capable of penetrating thin-walled materials such as color steel plates, galvanized plates, and aluminum alloys without damaging surface coatings.

3. Environmental Tolerance

Material Selection: Constructed from carbon steel (e.g., 1022A), stainless steel (304/410), or alloy steel, it meets diverse corrosion resistance requirements.

Surface Treatment: Includes processes such as white zinc plating, color zinc plating, black phosphating, etc., making it suitable for challenging environments like humidity and salt spray.

3. Typical Application Scenarios

1. Building Steel Structure

Color Steel Tile Fixation: Designed for securing color steel plates to keels on roofs and walls, its drill tail design mitigates water leakage risks associated with pre-drilling.

Light Steel Keel Assembly: Enhances construction speed by efficiently fixing keel nodes in partition and ceiling systems.

2. Manufacturing of Mechanical Equipment

Thin Plate Assembly: Ideal for connecting the side panels and frames of chassis and cabinets, it reduces drilling processes and associated costs.

Vibration Equipment Fastening: Used for securing motor bases, fan brackets, and other parts, with the Huasi anti-loosening function ensuring long-term stability.
