Nylon Phillips Pan Head Machine Screws M2–M6 — Non-Conductive Plastic Fasteners for Electronics and Light Assembly
Metal screws in electronics enclosures, PCB assemblies, or plastic housings can cause short circuits, galvanic corrosion, or cracked mounting bosses. For engineers, hobbyists, and makers who need a fastener that won't conduct electricity, won't rust, and won't damage delicate plastic components, nylon Phillips pan head machine screws are the practical solution. These plastic metric screws are designed for applications where electrical isolation, chemical resistance, or lightweight construction matters.
Each set includes nylon pan head machine screws in your chosen size, available in diameters from M2 (2mm / ≈5/64") through M6 (6mm / ≈15/64"), with thread lengths ranging from 5mm (≈3/16") to 40mm (≈1-9/16"). Pack sizes are 50 or 100 pieces depending on the size selected. All screws feature a Phillips (cross) drive recess and a low-profile pan head. The material is standard engineering nylon (polyamide), which is lightweight, non-magnetic, and resistant to most common chemicals and solvents.
These nylon machine screws are well-suited for PCB standoff and panel mounting in electronics enclosures, securing plastic covers and access panels in appliances, assembling RC car bodies and drone frames, and any application where a non-conductive metric Phillips pan head screw is needed to prevent electrical interference or galvanic corrosion.
🔩 Compatibility: ISO metric coarse thread — M2×0.4, M2.5×0.45, M3×0.5, M4×0.7, M5×0.8, M6×1.0. Compatible with standard metric nylon or metal nuts, threaded inserts, and tapped holes per ISO 68-1. Not compatible with UNC/UNF inch-standard fasteners.
⚠️ Nylon screws have lower torque limits than metal. Do not overtighten — nylon threads can strip more easily than steel. Hand-tighten and use a screwdriver, not a power drill, for best results.
✅ Key Features of These Nylon Phillips Pan Head Machine Screws
-
⚡Electrically Non-Conductive — Nylon is a natural electrical insulator, making these screws ideal for PCB mounting, electronics enclosures, and any assembly where preventing electrical contact between fastener and circuit is critical.
-
🛡️Corrosion-Proof Material — Unlike steel or zinc-plated fasteners, nylon will not rust, oxidize, or cause galvanic corrosion when used with aluminum, copper, or other dissimilar metals in humid or wet environments.
-
⚖️Lightweight Construction — Nylon screws weigh significantly less than equivalent metal fasteners, making them a practical choice for weight-sensitive applications such as drone frames, RC vehicles, and portable electronics.
-
✚Phillips Pan Head Profile — The low, rounded pan head distributes load evenly across plastic surfaces without cracking or deforming mounting bosses, and the Phillips drive is compatible with standard #0, #1, and #2 bits.
-
📏Wide Size Range — Available in M2, M2.5, M3, M4, M5, and M6 diameters with lengths from 5mm (≈3/16") to 40mm (≈1-9/16"), covering the most common nylon machine screw sizes used in electronics and light mechanical assembly.
-
📦Bulk Pack Options — Available in 50 or 100-piece packs, making it straightforward to stock up for production runs, repair kits, or ongoing maintenance without ordering individual fasteners.

❓ Frequently Asked Questions
How do I choose the right size nylon screw for my project?
Match the screw diameter to your tapped hole or nut size (M2, M2.5, M3, M4, M5, or M6). For length, the screw should engage at least 1.5× its diameter in the receiving material. For example, an M3 screw typically needs at least 4.5mm of thread engagement. Available lengths range from 5mm (≈3/16") to 40mm (≈1-9/16").
How strong are nylon machine screws compared to metal?
Nylon screws are generally lighter and less strong than metal fasteners. They are typically suitable for low-load, non-structural applications such as electronics enclosures, PCB standoffs, and plastic panel assembly. For applications requiring high clamping force or structural integrity, metal screws are generally recommended.
Are nylon screws suitable for outdoor use?
Nylon is inherently corrosion-proof and will not rust, making it suitable for humid, wet, or mildly corrosive outdoor environments. However, prolonged UV exposure can cause nylon to become brittle over time. For long-term outdoor use in direct sunlight, UV-stabilized nylon or other materials may be more appropriate.
Are these screws electrically non-conductive?
Yes. Nylon is an electrical insulator, making these screws suitable for use in electronics assemblies, PCB mounting, and applications where electrical isolation between components is required. They will not cause galvanic corrosion when used with dissimilar metals.
What thread standard do these nylon screws use — are they compatible with my nuts?
These screws use standard ISO metric coarse thread (M2, M2.5, M3, M4, M5, M6). They are compatible with standard metric nylon or metal nuts, threaded inserts, and tapped holes per ISO 68-1. They are not compatible with UNC/UNF inch-standard fasteners.
What screwdriver do I need for these screws?
These screws have a Phillips (cross) drive head. For M2–M3, a #0 or #1 Phillips bit is typically used. For M4–M6, a #2 Phillips bit is generally appropriate. Using the correct bit size is especially important with nylon screws to avoid stripping the head — always hand-tighten or use a low-torque driver setting.
Can I use these nylon screws with metal nuts or threaded inserts?
Yes. These nylon screws are compatible with standard metric metal nuts, nylon nuts, and threaded inserts of the corresponding size. They are commonly used with brass or stainless steel threaded inserts in plastic enclosures and PCB assemblies.
