Nylon Countersunk Phillips Screws — Non-Conductive, Rustproof PA66 Fasteners

When metal screws would cause shorts, corrode, or interfere with sensitive equipment, these PA66 nylon countersunk screws are the right call. Whether you're mounting a circuit board, securing a battery terminal, or assembling marine hardware, nylon eliminates the risks that metal introduces.

Made from PA66 (Nylon 66) engineering plastic, each screw features a 90° flat countersunk head that sits flush after proper countersinking, a standard Phillips cross-recess drive, and fully metric threading. Available in M2.5, M3, M4, M5, M6, and M8 diameters — with lengths typically ranging from 5 mm to 40 mm depending on size — and in pack quantities of 10, 50, 100, 500, or 1000 pieces.

Ideal for PCB mounting, 3D printer assemblies, electronics enclosures, marine equipment, chemical processing environments, and any application where electrical insulation or corrosion resistance is required.

✅ Compatible with standard metric countersunk holes (90° included angle, DIN 965 / ISO 7046). Works with M2.5, M3, M4, M5, M6, and M8 tapped or clearance holes in plastic, wood, aluminum, and PCB substrates.

✅ Key Features of These Nylon Countersunk Phillips Screws

⚡ Electrically Non-Conductive: PA66 nylon is a natural insulator — safe for PCB mounting, wire terminals, and ground-loop-sensitive assemblies.
🦀 100% Corrosion-Proof: No rust, no oxidation, no galvanic reaction. Performs reliably in marine, coastal, and chemical environments where even stainless steel can fail.
🔽 Flush Countersunk Head (90°): Flat head sits flush with the surface after countersinking — clean, snag-free finish for professional installations.
🔧 Phillips Cross-Recess Drive: Works with standard crosshead screwdrivers and bits. Good torque control without cam-out under moderate loads.
📏 Full Metric Range M2.5 to M8: Covers miniature electronics (M2.5) through light mechanical assemblies (M8) — select your exact size from the dropdown.
💪 PA66 Engineering Plastic: High mechanical strength, good toughness, abrasion and chemical resistant. Approximately 1/5 the weight of steel.

🎯 Who Is This For?

🖥️ Electronics & PCB Builders

Mount circuit boards, secure terminal blocks, and fasten battery holders without risk of shorts or ground loops. M2.5 and M3 sizes are especially popular for Raspberry Pi, Arduino, and custom PCB enclosures.

⛵ Marine & Outdoor Applications

Saltwater, humidity, and UV exposure destroy metal fasteners over time. Nylon screws hold up in boat hatches, marine radio mounts, and coastal equipment installations where corrosion is a constant concern.

🧪 Chemical & Industrial Environments

Resistant to many acids, alkalis, and solvents. Use in chemical processing equipment, laboratory fixtures, and industrial enclosures where metal contamination or corrosion is unacceptable.

🖨️ 3D Printing & Maker Projects

Lightweight, easy to cut or trim, and won't damage delicate printed parts. A go-to fastener for 3D printer frames, custom enclosures, and maker community builds.

❓ Frequently Asked Questions

Are these screws strong enough for structural applications?

Nylon screws have generally 1/5 to 1/3 the tensile strength of steel. They're well-suited for lightweight assemblies, electrical insulation, corrosion-prone environments, and vibration-damping. For heavy load-bearing applications, use metal fasteners. For PCB mounting, plastic enclosures, boat hatches, or battery terminals, nylon is typically ideal.

Do I need to countersink the hole before installing these screws?

Yes — for the head to sit flush, you need a matching 90° countersink hole. Use a countersink bit sized for the screw diameter. In soft plastics or wood, the head can sometimes be pressed in, but proper countersinking gives a cleaner, more reliable result.

How is the screw length measured?

Per DIN 965, the length is measured overall — from the top of the head to the tip. So an "M3 x 10mm" screw has a total length of 10 mm including the head.

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 typically slip before the screw breaks, but caution is advised.

Can these screws be used outdoors in direct sunlight?

Nylon is UV-sensitive and may become brittle or discolor with prolonged direct sunlight exposure over months or years. For shaded or indoor applications they perform well. For continuous outdoor UV exposure, consider UV-stabilized variants or protect the screw heads with UV-blocking paint or coating.

What is the difference between PA66 and PA6 nylon?

PA66 (Nylon 66) has higher mechanical strength, better stiffness, and a higher melting point than PA6. It is the standard choice for engineering fasteners where strength and temperature resistance are important.

Are these screws non-magnetic?

Yes — PA66 nylon is completely non-magnetic. These screws are safe to use near magnetic sensors, compasses, MRI-adjacent equipment, and other magnetically sensitive applications.
