Metal screws in electrical enclosures, PCB assemblies, and sensitive electronics create real risks — short circuits, galvanic corrosion, and RF interference. These black nylon PA66 pan head Phillips machine screws in M2 through M8 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 across the full M2–M8 range.
The pan head profile provides a wide, flat bearing surface that distributes clamping force evenly across thin panels, PCB surfaces, and plastic housings without digging in. Available in 7 diameters and lengths from 4mm (0.16”) to 60mm (2.36”), with pack sizes of 10, 20, and 50 pieces. The black color suits dark enclosures, electronics, and assemblies where a low-visibility fastener is preferred.
Typical applications include PCB standoff and component mounting (M2–M3), electronics enclosure assembly where metal screws would create short-circuit risk (M3–M5), plastic housing and panel fastening (M4–M6), RF and EMI-sensitive assemblies (M2–M4), and general DIY projects where electrical isolation or corrosion resistance is required (M4–M8).

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. Available lengths: 4mm (0.16”) to 60mm (2.36”) depending on the diameter. Not all lengths are available for every diameter — check the variant selector. 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 screwdriver matched to the screw size: PH0 for M2–M2.5, PH1 for M3–M4, PH2 for M5–M6, PH2 or PH3 for M8. Apply moderate torque only — nylon screws have lower torque limits than metal and can strip if overtightened. Hand-tight plus a quarter turn is typically sufficient.
Nylon PA66 has a tensile strength of typically 70–85 MPa — significantly lower than steel or stainless steel. These screws are designed for light-to-medium clamping loads in electronics, panels, 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 M-series hole or a matching metric nut in the same thread size. They will not cut their own thread into plastic or metal.
Available in packs of 10, 20, and 50 pieces. The 50-piece pack offers the best per-unit value for workshops and production use. Select your preferred quantity using the Pack Quantity option above.
