🔩 Product Overview: Transparent Nylon Phillips Round Head Screws – M3 to M6 (PA66)
Need a fastener that won't rust, won't conduct electricity, and won't scratch delicate surfaces? These transparent nylon Phillips round head machine screws are exactly what you're looking for. Made from PA66 nylon, they're lightweight, non‑conductive, and completely corrosion‑proof – perfect for electronics, battery compartments, medical devices, and outdoor gear where metal screws would cause problems. The clear, slightly translucent finish gives a clean, low‑profile look on panels and enclosures. Available in M3, M4, M5, and M6 metric diameters with a wide range of lengths (3mm to 20mm, measured under the head). Fully threaded with standard coarse pitch, these plastic screws are a smart alternative to metal for any project where insulation, weight, or chemical resistance matters.
✨ Why Choose Transparent Nylon Phillips Screws for Your Next Build
-
PA66 nylon material – Lightweight, non‑conductive, and completely corrosion‑proof. Won't rust or degrade in humid or outdoor environments. Chemically resistant to many solvents and oils.
-
Transparent / clear appearance – Blends in with clear or light‑colored panels. Less visible than metal or black plastic screws – great for displays and consumer electronics.
-
Phillips round head design – Low‑profile dome with a cross recess. Easy to drive with standard Phillips screwdrivers. Rounded top won't snag wires or fabric.
-
Metric sizes M3, M4, M5, M6 – Covers the most common small-to‑medium diameters for electronics enclosures, PCB mounting, and light machinery.
-
Wide length range (3mm–20mm under head) – Short screws for thin panels, longer ones for through‑hole applications. Common lengths: 3, 4, 5, 6, 8, 10, 12, 14, 15, 16, 18, 20mm (varies by diameter).
-
Fully threaded, metric coarse pitch – M3x0.5, M4x0.7, M5x0.8, M6x1.0. Threads run the entire length for maximum grip in plastic or with nuts.
-
Made in China to GB standards – Consistent dimensions and clean molding. Packaged in plastic bags or carton boxes.

❓ FAQs – Transparent Nylon Phillips Screws
🔸 Are these screws electrically insulating?
Yes – nylon is an excellent electrical insulator. These screws are non‑conductive, making them ideal for securing circuit boards, battery contacts, and sensitive electronics where metal screws could cause shorts.
🔸 Will nylon screws degrade in sunlight or heat?
Standard PA66 nylon is UV‑sensitive and can become brittle with prolonged direct sunlight. For outdoor use, try to keep them shaded or painted. They handle temperatures up to about 80–100°C (176–212°F) before softening. For extreme UV or high‑heat environments, look for specialty UV‑stabilized nylon.
🔸 How is length measured for these round head screws?
Length is measured from the underside of the head (the flat bearing surface) to the tip – the round head itself is not included. For example, an M4 x 10mm screw has a 10mm threaded shank below the head.
🔸 Can I use these screws with nuts, or are they self‑tapping?
These are machine screws – they are designed to be used with a matching metric nut (M3–M6) or screwed into a pre‑tapped metal or plastic hole. They are not self‑tapping. For plastic assemblies, you can also thread them directly into a slightly undersized pilot hole.
🔸 Are nylon screws strong enough for structural use?
Nylon screws are strong for plastic fasteners but not as strong as steel. Use them for non‑critical fastening: PCB mounting, battery covers, plastic enclosures, light furniture, and outdoor gear where corrosion is a concern. For load‑bearing or high‑torque applications, stick with metal.
🔸 What Phillips screwdriver size works for M3–M6 nylon screws?
M3: PH0 or PH1. M4: PH1. M5 and M6: PH2. Nylon is softer than metal, so don't overtighten – use light torque to avoid stripping the recess.
