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

FeatureDetailPurpose
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.

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.

Applications

PVC Slotted Pan Head Screws are commonly used in applications prioritizing chemical resistance and budget over high mechanical strength:

  1. Water Treatment and Plumbing: Securing components, strainers, and access covers in water purification equipment, pool systems, and non-pressurized lines.

  2. Chemical Containment: Fastening lightweight guards, labels, and covers on tanks and pipe systems handling ambient-temperature acids and bases.

  3. Laboratory Equipment: Assembling non-critical fixtures, racks, and enclosures in damp or chemical lab environments.

  4. Marine and Outdoor: Securing non-structural components exposed to humidity, rain, and saltwater spray.

Advantages

CategoryAdvantage (Pro)Disadvantage (Con)
PerformanceExcellent corrosion resistance against common chemicals. Highly economical.Low Mechanical Strength: Cannot withstand high tensile or shear loads; easily stripped.
MaterialLightweight and non-conductive. Widely available.Low Temperature Limit: Maximum continuous service temperature is typically low (60°C).
DesignPan Head provides superior load distribution.Slotted Drive Limitation: Provides low torque transmission and is prone to cam-out.

Packaging & Delivery
