⚪ Product Overview: White Nylon Plastic Pan Head Phillips Machine Screws – M3 to M6 (PA66)
Need a fastener that is non‑conductive, lightweight, and blends into light‑colored assemblies? These white nylon Phillips pan head machine screws are made from high‑quality PC (polycarbonate) / PA66 plastic – offering excellent electrical insulation, chemical resistance, and a clean, professional appearance. The round pan head provides a low‑profile bearing surface, while the Phillips drive works with standard #1 or #2 bits for easy installation. Fully threaded with standard coarse metric pitch, available in M3, M4, M5, and M6 diameters with lengths from 4mm to 60mm (measured under the head). Perfect for medical equipment, wind power, office machinery, marine industry, and any application where metal screws would cause shorts, rust, or add unwanted weight.
✨ Why Choose White Nylon Phillips Screws
-
High‑quality plastic (PC / PA66) – Colorless / white, transparent to semi‑transparent. Heat‑resistant, impact‑resistant, flame‑retardant (UL94 V‑2/BI grade).
-
Chemically resistant – Resists weak acids, weak alkalis, neutral oils. Won't degrade in many industrial and laboratory environments.
-
Electrically insulating & non‑magnetic – Perfect for electronics, battery compartments, and medical devices where metal screws could cause shorts or interference.
-
Low‑profile pan (round) head – Rounded top with a flat bearing surface. Sits flush on panels and distributes clamping force evenly.
-
Metric sizes M3, M4, M5, M6 – Covers the most common diameters for appliances, electronics, marine equipment, and light machinery.
-
Lengths from 4mm to 60mm (under head) – Short screws for thin panels, longer ones for through‑hole assemblies. Choose exactly what you need.
-
Fully threaded, coarse metric pitch – Standard threads: M3x0.5, M4x0.7, M5x0.8, M6x1.0. Threads run the entire shank length for maximum grip.
-
Wide application range – Medical equipment, wind power generation, office machinery, marine industry, electronics, and general assembly.

❓ FAQs – White Nylon Phillips Screws
🔸 Are these screws electrically insulating?
Yes – nylon/PC plastic is an excellent electrical insulator. These screws are completely non‑conductive, making them perfect for securing circuit boards, battery contacts, and sensitive electronics where metal screws could cause shorts or grounding issues.
🔸 Will nylon screws degrade in sunlight or outdoor use?
Standard 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 120°C (248°F) before softening. For extreme UV exposure, consider UV‑stabilized nylon (available by request).
🔸 How strong are nylon screws compared to steel?
Nylon screws are strong for plastic fasteners but not as strong as steel. Use them for non‑critical fastening: PCB mounting, battery covers, medical device housings, light machinery, and marine electronics where corrosion or conductivity is a concern. For load‑bearing or high‑torque applications, stick with metal.
🔸 How is length measured for these pan head screws?
Length is measured from the underside of the head (the flat bearing surface) to the tip, not including the pan head. For example, an M5 x 20mm screw has a 20mm threaded shank. This is standard for pan head machine screws.
🔸 Can I use these screws with nuts, or are they self‑tapping?
These are machine screws – they require a matching metric nut (M3–M6) or a pre‑tapped hole. They are not self‑tapping. For best results, use nylon nuts (recommended) or stainless steel nuts.
🔸 What Phillips screwdriver size works for M3 through M6?
M3–M4: use PH1. M5–M6: use PH2. Nylon is softer than metal, so don't overtighten – use light torque to avoid stripping the recess.
