### 1. **Product Portfolio & Specifications**
- **Material**: 304 stainless steel (A2 grade, 18Cr-8Ni) for corrosion resistance and durability.
- **Size Range**: M4, M5, M6, M8, M10, M12, M14, M16 (metric diameters) with lengths from 10–100mm.
- **Dual Design Types**:
- **Hexagonal Socket Head Screws**: Conform to ISO 4762 (cylindrical head with internal hex drive).
- **Anti-Slip Cylindrical Head Bolts**: External hex drive option with textured surfaces for grip.
### 2. **Design Features for Anti-Slip & Dispensing**
- **Anti-Slip Mechanisms**:
- **Knurled Shank**: Diamond-pattern knurling on shank (M6+ sizes) to prevent rotational slip in soft materials.
- **Toothed Under-Head**: Serrated washer face reduces torque loss on smooth surfaces (e.g., aluminum panels).
- **Dispensing-Optimized Design**:
- **Flush Cylindrical Head**: Low-profile design (head height = 0.7×d) minimizes obstruction in dispensing equipment.
- **Thread Pitch**: Fine threads (e.g., M6×1.0) for precise adjustment in syringe/pump assemblies.
### 3. **Technical Specifications**
- **Thread Standards**:
- Metric coarse (ISO 68-1) or fine (ISO 13670) threads with 6g tolerance.
- **Mechanical Properties**:
- Tensile strength: ≥520 MPa; yield strength: ≥205 MPa (annealed 304).
- **Head Dimensions**:
- Hex socket drive: per ISO 4762 (e.g., M6 socket = 5mm key size).
- Cylindrical head diameter: 1.5×d (e.g., M6 head = 10mm).
### 4. **Surface Treatment & Corrosion Resistance**
- **Passivated Finish**: Standard (ASTM A967) to enhance corrosion resistance (500+ hours salt spray).
- **Optional Coatings**:
- PTFE (Teflon) for low friction in moving parts; black oxide for anti-glare in optical systems.
### 5. **Applications in Dispensing & Industrial Settings**
- **Adhesive Dispensing Equipment**:
- Securing syringe barrels, pump heads, and valve assemblies in automated dispensing systems.
- **Electronic & Medical Devices**:
- Mounting components in PCB assemblies, diagnostic equipment (biocompatible 304 for medical use).
- **Precision Machinery**:
- High-torque applications requiring slip resistance (e.g., robotic arms, CNC machinery).
### 6. **Installation Advantages**
- **Torque Efficiency**:
- Internal hex drive allows 30% higher torque compared to Phillips heads (ISO 15330 testing).
- **Vibration Resistance**:
- Anti-slip features reduce loosening in dynamic environments (tested to 20G vibration).
### 7. **Quality Assurance & Certifications**
- **Testing**:
- Tensile, hardness, and thread gauge checks (ISO 9001 compliant).
- **Compliance**:
- RoHS/REACH, CE marking; material test reports (MTRs) available.
### 8. **Packaging & Supply**
- **Bulk Sets**: 50–1,000 kits per carton with moisture protection.
- **In-Stock Items**: M4–M12 standard lengths ready for same-day shipping.
### 9. **Customization Options**
- **Non-Standard Features**:
- Thread-locking (Loctite 242), anti-seize coatings, or laser-engraved part numbers.
