Metal screws in electrical enclosures, PCB assemblies, and sensitive electronics create real risks — short circuits, galvanic corrosion, and RF interference. These M3 black nylon pan head Phillips machine screws eliminate those risks. Made from engineering-grade nylon (PA66), they are fully non-conductive, corrosion-resistant, and lightweight — the standard choice for electronics assembly, PCB mounting, and precision plastic housings.
The pan head profile provides a wide, flat bearing surface that distributes clamping force without digging into plastic panels or PCB surfaces. Available in lengths from 4mm (0.16”) to 30mm (1.18”) and pack sizes from 10 to 500 pieces — whether you need a handful for a one-off repair or a bulk supply for production runs, select exactly what you need.
Typical applications include PCB standoff and component mounting, electrical enclosure assembly where metal screws would create short-circuit risk, plastic housing and panel fastening, RF and EMI-sensitive assemblies, and any DIY project where electrical isolation or corrosion resistance is required.

Measure the depth of the tapped hole or the thickness of the material being clamped. The screw length (excluding head) should engage at least 1.5× the thread diameter — at least 4.5mm for M3. Available lengths: 4mm (0.16”) to 30mm (1.18”). When in doubt, size up.
Engineering-grade nylon (PA66 / Polyamide 66) — durable, lightweight, non-conductive, and corrosion-resistant. PA66 is the standard material for plastic fasteners in electronics, PCB, and precision instrument applications.
Yes. Nylon is a non-conductive material, making these screws ideal for PCB mounting, electrical enclosures, and any application where electrical isolation is required. They eliminate the short-circuit and galvanic corrosion risks associated with metal fasteners in electronics assemblies.
A Phillips PH2 screwdriver. Apply moderate torque only — nylon screws have lower torque limits than metal screws and can strip if overtightened. Hand-tight plus a quarter turn is typically sufficient. Do not use a power driver at high torque settings.
Nylon PA66 has a tensile strength of typically 70–85 MPa — significantly lower than steel or stainless steel. These screws are designed for light clamping loads in electronics, PCB, and plastic assemblies, not for structural or high-load applications. Do not overtighten.
Nylon is corrosion-resistant and moisture-resistant, making it suitable for light outdoor use. Prolonged UV exposure may cause gradual degradation over time — for long-term outdoor use, consider UV-stabilized nylon variants.
Yes — these are machine screws, not self-tapping. They require a pre-tapped M3 hole, an M3 nut, or an M3 threaded insert. They will not cut their own thread into plastic or metal.
Available in packs of 10, 30, 50, 80, 100, 200, 300, and 500 pieces. Larger packs offer better per-unit value for production runs and workshop stock. Select your preferred quantity using the Pack Quantity option above.
