⚪ Nylon Phillips Round Pan Head Machine Screws – M2 M2.5 M3 M4, Non‑Conductive & Corrosion‑Free
You’re mounting a PCB, securing a battery holder, or assembling a marine radio – and metal screws could cause shorts or rust over time. These nylon Phillips round pan head machine screws are molded from tough engineering plastic that’s completely non‑conductive, non‑magnetic, and immune to corrosion. The round pan head provides a wide bearing surface, perfect for plastic enclosures, thin wood, or sheet metal. Phillips drive works with standard crosshead screwdrivers. Available in M2, M2.5, M3, and M4 diameters with lengths measured under the head (excluding the head). Fully threaded. Ideal for electronics, model making, medical devices, and any application where insulation or rust‑proofing is critical.
✨ Key Features – Nylon Phillips Round Pan Head Screws
- ⚡ Electrically insulating – Nylon is a natural insulator. Safe for PCBs, terminal blocks, and live circuits.
- 🦀 100% corrosion‑proof – No rust, no oxidation, no galvanic reaction. Perfect for marine, chemical, and outdoor environments.
- 🔘 Round pan head design – Low profile with a wide bearing surface. Distributes clamping force evenly – ideal for soft materials.
- ⚡
Phillips drive – Standard cross recess works with common screwdrivers. Good torque control for hand assembly.
- 📏 Metric sizes M2, M2.5, M3, M4 – Perfect for small to medium fastening in electronics, hobby projects, and light machinery.
- 📐 Lengths measured under head (excluding head) – Example: M3 x 10mm means thread diameter 3mm, length from under head to tip is 10mm. Fully threaded.
- 💪 PA66 engineering plastic – High mechanical strength, good toughness, abrasion and chemical resistant. Lightweight (about 1/5 the weight of steel).

❓ Frequently Asked Questions – Nylon Phillips Round Pan Head Screws
1. Are these screws strong enough for structural applications?
Nylon screws have about 1/5 to 1/3 the tensile strength of steel. They are perfect for lightweight assemblies, electrical insulation, corrosion‑prone environments, and vibration‑damping. For heavy load‑bearing (e.g., holding a 50kg shelf), use metal. For PCB mounting, plastic enclosures, boat hatches, or battery terminals, nylon is ideal.
2. Can I use these screws outdoors? Will they degrade in sunlight?
Nylon is UV‑sensitive. For continuous outdoor sunlight exposure (months or years), the material may become brittle and discolor. We recommend using them in shaded or indoor applications, or painting the screw heads with UV‑blocking paint for outdoor use. For marine or outdoor use where UV is a concern, consider black nylon (which has added UV stabilizers).
3. How do I measure the length of a round pan head screw?
For pan head screws, length is measured from the underside of the head (the flat bearing surface) to the tip. The head itself is NOT included. So an “M3 x 10mm” screw has a 10mm long threaded shaft under the head. Our listing follows this standard.
4. Can I use a power drill to drive these screws?
Yes – but use a very low‑clutch setting (1–2) and low speed. Nylon threads can strip if over‑torqued. Hand tightening is recommended for final seating. The Phillips drive will slip before the screw breaks, but caution is advised.
5. Can I use these screws with a nut? What size nut fits?
Yes – these are machine screws. Use standard metric nuts of the same thread size (e.g., M3 nut for M3 screw). They will also thread into pre‑tapped holes. They are not self‑tapping – for wood or plastic, drill a pilot hole and use a nut or threaded insert.
6. Do you offer other sizes like M5 or M6 in nylon?
This listing covers M2 to M4. We also carry nylon screws in M5, M6, M8, and M10 – please check our store or contact us for availability.
