Nylon Machine Screws M2–M4 | Non-Conductive Pan, Flat & Socket Cap Head Fasteners with Hex Nut & Cap Nut Options
When metal screws risk short-circuiting your PCB, corroding in a chemical environment, or adding unwanted weight to a precision build, you need a reliable non-metallic alternative. These PA66 nylon machine screws are engineered for electronics assembly, robotics, 3D printer frames, and any application where insulation, corrosion resistance, or weight savings matter.
Made from Grade 4.8 PA66 nylon, this listing covers six product types: Pan Head Phillips Screws, Flat Head Phillips Screws, Socket Cap Head Hex Screws, Screw + Hex Nut + Washer combo sets, Cap Nuts (Dome Nuts), and Hex Nuts. Thread sizes range from M2 to M4, with lengths from 4mm to 40mm (0.16" to 1.57"), available in White, Black, and Clear.
Ideal for PCB and electronics enclosure mounting (zero conductivity risk), chemical and corrosion-sensitive assemblies (aquariums, lab equipment, outdoor fixtures), and lightweight mechanical builds (drones, RC models, 3D printer frames). The self-lubricating surface reduces friction during installation, and the non-magnetic properties make them safe near sensitive sensors.
🔩 Compatibility: Metric coarse right-hand thread · M2 / M2.5 / M3 / M4 tapped holes · Phillips #1 or #0 bit (pan/flat head) · 2.5mm or 3mm hex key (socket cap head)
⚠️ PA66 nylon is rated for continuous use up to approximately 85–100°C. Not recommended for high-torque structural applications. Slight color variation may occur between batches — refer to the actual product.

❓ Frequently Asked Questions
What material are these screws made from?
These screws are made from PA66 nylon (Grade 4.8), which is non-conductive, non-magnetic, lightweight, and chemically resistant — ideal for electronics, PCB assemblies, and corrosion-sensitive environments.
What sizes are available?
Available in M2, M2.5, M3, and M4 thread sizes, with lengths ranging from 4mm to 40mm depending on the product type selected.
What product types are included in this listing?
This listing covers Pan Head Phillips Screws, Flat Head Phillips Screws, Socket Cap Head Hex Screws, Screw + Hex Nut + Washer combo sets, Cap Nuts (Dome Nuts), and Hex Nuts — all in nylon.
Are nylon screws electrically insulating?
Yes. PA66 nylon is an excellent electrical insulator, making these screws well-suited for PCB mounting, electronics enclosures, and any application where metal fasteners could cause short circuits.
What colors are available?
Available in White, Black, and Clear (transparent), depending on the size and product type selected. Color availability varies by variant.
What thread type do these screws use?
All screws use metric coarse right-hand thread, which is the standard for M2–M4 fasteners in most DIY, electronics, and mechanical applications.
Can I use these screws in high-temperature environments?
PA66 nylon is generally rated for continuous use up to approximately 85–100°C (185–212°F). For higher temperature applications, consider metal fasteners or higher-grade engineering plastics.
