🔩 Product Overview: Transparent Plastic Phillips Pan Head Screws – M2 to M8 (PC Material)
Need a fastener that won't corrode, won't conduct electricity, and is nearly invisible on clear panels? These transparent plastic Phillips pan head machine screws are made from high‑quality PC (polycarbonate) – a durable engineering plastic with excellent impact resistance, heat resistance, and flame retardancy (UL94 V‑2/BI grade). The clear, colorless finish blends seamlessly into transparent enclosures, medical devices, and electronics. Available in metric sizes from M2 up to M8, with lengths from 4mm to 50mm (measured under the head). Fully threaded with standard coarse pitch, they resist weak acids, weak alkalis, and neutral oils. Perfect for medical equipment, wind power, marine, office machinery, and any application where metal screws would short circuit, rust, or spoil the look.
✨ Why Choose PC Plastic Phillips Pan Head Screws
-
High‑quality PC (polycarbonate) material – Colorless and transparent, heat‑resistant, impact‑resistant, and flame‑retardant (BI grade). A general‑purpose engineering plastic with good mechanical properties in normal use temperatures.
-
Chemically resistant – Resists weak acids, weak alkalis, and neutral oils. Won't degrade in many industrial and laboratory environments.
-
Electrically insulating – Non‑conductive, making them ideal for electronics, battery compartments, and any application where metal screws could cause shorts.
-
Phillips pan head design – Low‑profile rounded head with a flat bearing surface. Distributes clamping force evenly and blends into clear panels or light‑colored assemblies.
-
Wide metric range: M2, M2.5, M3, M4, M5, M6, M8 – From tiny electronics up to medium‑duty equipment. One product line covers most plastic fastening needs.
-
Lengths from 4mm to 50mm (under head) – Short screws for thin panels, longer ones for through‑hole applications. Choose exactly what your project requires.
-
Fully threaded, coarse metric pitch – Standard threads: M2x0.4, M2.5x0.45, M3x0.5, M4x0.7, M5x0.8, M6x1.0, M8x1.25. Threads run the entire shank length.
-
Wide application range – Medical equipment, wind power generation, office machinery, marine industry, and many other fields.

❓ FAQs – Transparent Plastic Phillips Screws
🔸 Are these screws electrically insulating?
Yes – 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.
🔸 How strong are PC plastic screws compared to metal?
PC plastic screws are strong for engineering plastic fasteners but not as strong as steel. They have good impact resistance and mechanical properties within normal temperature ranges. Use them for non‑critical fastening: PCB mounting, battery covers, medical device housings, and light industrial equipment where corrosion or conductivity is a concern. For load‑bearing or high‑torque applications, stick with metal.
🔸 Will transparent PC screws yellow or degrade over time?
PC plastic can yellow slightly with prolonged UV exposure (direct sunlight). For indoor use or behind UV‑blocking panels, they remain clear for a long time. They are heat‑resistant and impact‑resistant. If outdoor UV exposure is a concern, consider opaque or UV‑stabilized plastic screws.
🔸 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 M4 x 12mm screw has a 12mm 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 (M2–M8) or a pre‑tapped hole. They are not self‑tapping. For plastic assemblies, you can also thread them directly into a slightly undersized pilot hole in soft plastic (the screw will cut its own threads). For best results, use a threaded insert or a nut on the back side.
🔸 What Phillips screwdriver size works for M2 through M8?
M2–M2.5: use PH00 or PH0. M3–M4: use PH1. M5–M6: use PH2. M8: use PH2 or PH3 (PH2 works for most). PC plastic is softer than metal, so don't overtighten – use light torque to avoid stripping the recess.
