What Are Plastic Fasteners?｜Key Advantages and Materials of Plastic Hardware

Plastic fasteners are lightweight, non-conductive, and resistant to rust and chemicals—making them ideal for electronics, medical devices, and industrial machinery. Learn the core strengths and best-use materials in this guide.
1. What Is Plastic Hardware?
Plastic hardware—commonly known as plastic fasteners—includes screws, nuts, washers, and related components made from engineering plastics rather than metal. These are used in industries such as electronics, medical devices, chemical processing, and precision equipment.
Plastic fasteners offer key benefits over metal: they do not conduct electricity, resist corrosion, and weigh significantly less. These features make them essential for applications that demand insulation, non-magnetic properties, and reduced weight.
2. Key Plastic Materials and Their Properties
- PPS (Polyphenylene Sulfide)
Excellent chemical and heat resistance. Ideal for semiconductor systems and chemical plant machinery.
- PC (Polycarbonate)
Transparent and impact-resistant. Used in visible or safety-critical parts of medical and electronic equipment.
- PA (Polyamide/Nylon)
Strong and abrasion-resistant. Widely applied in general machinery, though it can absorb moisture, which affects precision.
- PEEK (Polyether Ether Ketone)
Withstands temperatures up to 250°C and harsh chemicals. Perfect for aerospace, high-end medical tools, and ultra-precision components.
3. Strengths of Plastic Fasteners
- Lightweight – Lowers total system weight and boosts energy efficiency
- Electrical Insulation – Safe for sensitive electronics and circuit boards
- Chemical Resistance – Performs in harsh chemical environments
- Non-Magnetic – Prevents magnetic interference in precision instruments
- Corrosion-Free – Suitable for outdoor or humid environments
4. Important Usage Considerations
- Lower tensile strength and torque vs. metal counterparts
- Heat resistance depends on plastic type—critical for material selection
- Some types (like Nylon) absorb moisture, affecting dimensions
- Susceptible to UV degradation if not UV-stabilized for outdoor use
