Here’s a detailed point-by-point description in English with technical specifications, design features, and application insights:
### 1. **Product Range & Sizes**
- **Metric Diameters**: M6, M8, M10, M12, M14, M16 (standard metric sizes for versatile anchoring).
- **Length Options**: 30–300mm (custom lengths available for deep concrete installations).
- **Designation**: "Thunderbolt" refers to high-speed installation and heavy-duty performance in concrete substrates.
### 2. **Design & Structural Features**
- **Hexagon Head**:
- 6-point drive (ISO 4014) for wrench/socket engagement, enabling high torque application.
- Reinforced head thickness to prevent deformation during impact installation.
- **Self-Tapping Threads**:
- Aggressive, saw-tooth thread profile (patented design) cuts through concrete without pre-drilling.
- Reverse cutting edges reduce torque resistance and prevent concrete spalling.
- **Anchoring Mechanism**:
- Expanding shank design (post-installation expansion) creates mechanical interlock with concrete.
- Pre-installed expansion sleeve (for M10+ sizes) enhances pull-out resistance.
### 3. **Material & Surface Treatment**
- **Core Material**:
- High-carbon steel (C45, 1045) quenched & tempered to 8.8 grade (tensile strength ≥800 MPa).
- **Corrosion Protection**:
- Zinc plating (8–12μm) for 500+ hours salt spray resistance (ASTM B117).
- Optional Dacromet coating for marine/chemical environments (1,000+ hours salt spray).
### 4. **Technical Specifications**
- **Thread Type**:
- Specialized concrete-cutting threads (pitch: M6=1.0mm, M16=2.0mm) for rapid penetration.
- **Load Ratings (C25 Concrete)**:
- **Pull-out Force**: M12: ≥18 kN; M16: ≥32 kN (tested per EN 1992-4).
- **Shear Strength**: M12: ≥15 kN; M16: ≥28 kN (dynamic load capacity).
- **Drill Bit Compatibility**:
- Pre-drilling optional for hard concrete (recommended hole diameter = bolt diameter + 1mm).
### 5. **Installation Advantages**
- **Tool-Free Option**:
- Installable with impact wrenches or hammer drills (no need for anchor setting tools).
- **Time-Saving**:
- 30% faster installation than traditional expansion anchors (no pre-drilling or sleeve insertion).
- **Vibration Resistance**:
- Thread locking design prevents loosening in seismic zones (tested to 4.5 Richter scale equivalent).
### 6. **Applications**
- **Construction**:
- Steel frame anchoring, curtain wall installations, and precast concrete connections.
- **Infrastructure**:
- Bridge bearings, tunnel fixtures, and highway guardrail mounting.
- **Industrial**:
- Machinery baseplates, conveyor systems, and equipment anchoring in factories.
- **Renovation**:
- Retrofit projects (e.g., adding anchors to existing concrete without core drilling).
### 7. **Standards & Certifications**
- **Compliance**:
- EN 14592 (mechanical anchors in concrete), ISO 898-1 (fastener mechanical properties).
- **Test Reports**:
- Available for fire resistance (up to 900°C), freeze-thaw cycles, and chemical exposure.
### 8. **Packaging & Supply**
- **Bulk Packaging**:
- 50/100/500-piece cartons with moisture-proof bags; palletized for orders ≥1,000 pcs.
- **Lead Times**:
- Standard sizes (M6–M16) in stock for same-day shipping; custom lengths ready in 5–7 days.
### 9. **Safety & Usage Tips**
- **Installation Precautions**:
- Wear eye protection; maintain perpendicular angle to concrete surface.
- **Environmental Limits**:
- Suitable for -40°C to +120°C; avoid direct contact with acidic solutions (pH <4).
### 10. **Comparative Advantages**
- **vs. Traditional Anchors**:
- Eliminates need for expansion sleeves, reducing component costs by 20%.
- **vs. Self-Drilling Screws**:
- 3x higher pull-out strength in cracked concrete (tested per ETAG 001).
