CPVC Hexagon head bolt Overview
CPVC (Chlorinated Polyvinyl Chloride) Hexagon Head Bolt is a robust plastic bolt utilized in industrial and chemical processing applications. It features a traditional hexagonal head, which is externally driven with a wrench, allowing for a higher clamping force compared to slotted or Phillips-driven screws made of the same material.
Overview and Design
| Feature | Detail | Purpose |
| Material | CPVC (Chlorinated Polyvinyl Chloride) | Provides excellent chemical stability and a higher operating temperature range than standard PVC. |
| Head Style | Hexagon Head | The six-sided head is designed for maximum external wrench grip, enabling the highest torque and clamping force achievable with a CPVC fastener. |
| Application | Through-hole fastening (requires a nut, often a CPVC Hex Nut) or heavy-duty threading into a pre-tapped component. | Ideal for medium-stress, chemically resistant structural assemblies. |
Key Characteristics
CPVC Hexagon Head Bolts provide an essential balance between performance and cost in corrosive environments:
Excellent Chemical Resistance: Highly stable against most mineral acids, bases, salts, and common water treatment chemicals.
Good Thermal Tolerance: Suitable for service temperatures that exceed the limits of standard PVC (often up to 90°C).
Corrosion Immunity: Will not rust, corrode, or cause galvanic reactions when wet, unlike metal bolts.
Electrical Insulation: Inherently non-conductive, making it safe for mounting electrical components.2
Cost-Effectiveness: A more economical choice than high-performance fluoropolymers (like PVDF or PEEK) while offering reliable resistance.
Product Parameters
CPVC Hexagon Head Bolts typically follow established standards like ISO 4014 (partially threaded) or ISO 4017 (fully threaded).
| Nominal Diameter (d) | Thread Pitch (P) | Across Flats (s) | Head Height (k) |
| M4 | 0.7 mm | 7.0 mm | 2.8 mm |
| M6 | 1.0 mm | 10.0 mm | 4.0 mm |
| M8 | 1.25 mm | 13.0 mm | 5.3 mm |
| M10 | 1.5 mm | 16.0 mm | 6.4 mm |
| M12 | 1.75 mm | 18.0 mm | 7.5 mm |
Advantages and Disadvantages
| Category | Advantage (Pro) | Disadvantage (Con) |
| Design | Hex Head allows for the highest torque and clamping force achievable with CPVC material. | Requires external tooling (wrench/spanner) for installation. |
| Performance | Excellent corrosion resistance; reliable temperature performance above standard PVC. | Low Mechanical Strength: Cannot withstand the high tensile or shear loads of metal fasteners. |
| Material | Cost-effective, lightweight, and non-contaminating. | Torque Limit: Over-tightening can easily strip the plastic threads or fracture the head. |
