Product Description

Experience the efficiency and dependability of the Hexagonal pointed cutting tail screw, an innovative fastener designed to blend seamless installation with robust fastening capabilities. Below are its core design features and performance advantages.

1. Structural Features
  • Hexagonal Head Design: Perfectly aligns with standard wrenches or power tools for stable torque transmission and precise installation.
  • Integrated Spring Washer (Huasi): Counters looseness caused by vibrations or impacts through elastic deformation, maintaining steadfast stability.
  • Sharp Cut Tail Design: Features a drill point that penetrates metal plates (≤ 6mm), wood, and plastic without pre-drilling.
2. Performance Advantages
  • Construction Efficiency: Integrates drilling, tapping, and locking into a single process, increasing efficiency by over 50%.
  • Triple Anti-Loosening: Combines hexagonal torque control, elastic compensation, and high-bite thread engagement.
  • Environmental Durability: Available in high-strength stainless steel or galvanized carbon steel for superior corrosion resistance.
3. Application & Selection

Typical Scenarios: Building steel hooks, mechanical equipment manufacturing, automotive transportation, and the electronics industry.

Selection Criteria: Ideal for single-layer metal plates ≤ 6mm. Choose stainless steel for dynamic loads/vibrating equipment, and galvanized carbon steel for static loads.

Frequently Asked Questions
Q: Can these screws penetrate metal without pre-drilling? A: Yes, the sharp cut tail (drill tail) design allows the screw to penetrate metal plates with a thickness of up to 6mm automatically.
Q: What materials are these hexagonal screws made from? A: They are typically manufactured from high-strength stainless steel (304 or 316) or carbon steel with galvanized/Dacromet surface treatments.
Q: What is the benefit of the integrated washer (Huasi)? A: The integrated spring washer provides elastic compensation to prevent loosening in high-vibration environments.
Q: Are these screws compatible with standard electric power tools? A: Absolutely. The hexagonal head is designed to fit standard wrenches and electric drivers for high-torque installation.
Q: Which industry uses these fasteners the most? A: They are widely used in steel structure construction, mechanical assembly, automotive manufacturing, and HVAC installations.
