FAQ
What are plastic screws?
Plastic screws are fasteners made from various engineering plastics through injection molding or machining. Common materials include nylon (PA), polypropylene (PP), polyvinyl chloride (PVC), polytetrafluoroethylene (PTFE), and PEEK.
What are the main advantages of plastic screws?
- Corrosion resistance: Resistant to acids, alkalis, salts, and other chemicals; does not rust.
- Lightweight: Weighs only 1/4 to 1/8 of metal.
- Electrical insulation: Non-conductive, ensuring electrical safety.
- Non-magnetic: Unaffected by magnetic fields.
- Low cost: Raw material and processing costs are generally lower
What types of plastic screw heads are available?
Classification by Head Shape：Head type, pan head, countersunk/flat head, semi-countersunk head, round/semi-round head, flat round/large round head, hexagonal head, washer head
How to choose the right plastic screw material?
- Nylon (PA6, PA66): A general choice; good overall performance in terms of strength, toughness, and wear resistance.
- Polypropylene (PP): Excellent chemical resistance (especially acids and alkalis); inexpensive.
- PVC: Good corrosion resistance and flame retardancy.
- PTFE: Extremely high chemical resistance, extremely low coefficient of friction (non-stick), high temperature resistance (-200°C to +260°C).
- PEEK: Extremely high strength, hardness, and heat resistance (long-term use >250°C), expensive.
Application Scenarios of Plastic Screws
Plastic screws, due to their unique material properties, play an irreplaceable role in many scenarios where metal screws are unsuitable.
1. Chemical and Environmental Protection Industries
2. 1. Food, Pharmaceuticals & Medical Devices
2. Electronics, Electrical & Telecommunications
3. Automotive & Transportation
4. Semiconductors & Photovoltaics
5. Specialty Industrial Applications
Are plastic screws insulated?
Yes, this is one of their key advantages. They are complete electrical insulators, making them ideal for electronic and electrical applications.
How to screw in a plastic screw?
- For self-tapping screws, a properly sized guide hole needs to be pre-drilled in the substrate.
- Use a manual torque screwdriver or a low-torque electric screwdriver.
- Ensure the screw is perpendicular to the hole.
- Tighten until you feel noticeable resistance, then tighten slightly more; do not force it all the way in.
Can you provide samples?
Most professional manufacturers (including us) offer sample services so you can test and verify the suitability of the product. You will usually need to bear the shipping costs.
Can non-standard sizes and colors be customized?
Yes. This is a major advantage of plastic parts. Various non-standard sizes, head shapes, and colors (by adding color masterbatch) of screws can be produced through injection molding or machining to meet your specific design requirements.
What is the delivery time for plastic screws?
- Standard parts: Usually in stock, delivery is fast (a few days to a week).
- Custom parts: take longer because they involve mold making or production scheduling (usually 2-4 weeks or longer).
