PVC Slotted pan head screw Overview
PVC (Polyvinyl Chloride) Slotted Pan Head Screw is a widely used, economical plastic screw primarily valued for its excellent corrosion resistance against most chemicals at ambient temperatures. The Pan Head design provides a generous bearing surface for effective clamping, while the Slotted Drive allows for simple, conventional installation.
I. Overview and Design
| Feature | Detail | Purpose |
| Material (PVC) | Polyvinyl Chloride. A cost-effective thermoplastic known for its rigidity and chemical resistance to most acids and alkalis. | Provides a fastener that is immune to rust and galvanic corrosion at a lower cost than high-performance polymers. |
| Head Style (Pan Head) | Features a gently rounded top and vertical sides, maximizing the bearing surface for strong clamping and resistance to pull-through. |
Product Parameters
PVC Slotted Pan Head Screws typically follow metric standards for slotted pan head screws, such as ISO 1580 or similar industry specifications.
| Nominal Diameter (d) | Thread Pitch (P) | Head Diameter (D) | Head Height (K) | Slot Width (N) |
| M3 | 0.5 mm | 6.0 mm | 2.0 mm | 0.8 mm |
| M4 | 0.7 mm | 8.0 mm | 2.6 mm | 1.0 mm |
| M5 | 0.8 mm | 9.5 mm | 3.3 mm | 1.2 mm |
| M6 | 1.0 mm | 11.0 mm | 3.9 mm | 1.6 mm |
| M8 | 1.25 mm | 14.0 mm | 5.2 mm | 2.0 mm |
| M10 | 1.5 mm | 17.0 mm | 6.0 mm | 2.5 mm |
Key Features
PVC fasteners are defined by their combination of chemical resistance and low cost:
Excellent Chemical Resistance: Highly stable against most mineral acids and bases at room temperature, making it ideal for chemical plumbing.
Corrosion Immunity: Will not rust or cause galvanic corrosion, lasting indefinitely in wet or corrosive atmospheres.
Low Cost: One of the most economical corrosion-resistant fasteners available, suitable for large projects.
Good Rigidity: Provides sufficient stiffness for low-load fastening tasks.
Wide Bearing Surface: The Pan Head offers good pull-through resistance.
Key Polyvinyl Chloride (PVC) Properties
Applications
PVC Slotted Pan Head Screws are commonly used in applications prioritizing chemical resistance and budget over high mechanical strength:
Water Treatment and Plumbing: Securing components, strainers, and access covers in water purification equipment, pool systems, and non-pressurized lines.
Chemical Containment: Fastening lightweight guards, labels, and covers on tanks and pipe systems handling ambient-temperature acids and bases.
Laboratory Equipment: Assembling non-critical fixtures, racks, and enclosures in damp or chemical lab environments.
Marine and Outdoor: Securing non-structural components exposed to humidity, rain, and saltwater spray.
Advantages
| Category | Advantage (Pro) | Disadvantage (Con) |
| Performance | Excellent corrosion resistance against common chemicals. Highly economical. | Low Mechanical Strength: Cannot withstand high tensile or shear loads; easily stripped. |
| Material | Lightweight and non-conductive. Widely available. | Low Temperature Limit: Maximum continuous service temperature is typically low (60°C). |
| Design | Pan Head provides superior load distribution. | Slotted Drive Limitation: Provides low torque transmission and is prone to cam-out. |
