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. The Phillips drive (PH2) allows controlled tightening — just remember that nylon has lower torque limits than metal, so a snug fit is all you need.
Available in lengths from 4mm to 30mm 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.
Compatibility: M3 ISO metric thread. Phillips PH2 drive. Compatible with M3 tapped holes, M3 hex nuts, and M3 threaded inserts. Requires pre-tapped hole — not self-tapping.
Note: Nylon screws have lower torque limits than metal. Do not overtighten — hand-tight plus a quarter turn is typically sufficient. Size format: M3 × [length]mm (e.g., M3 × 10 = 3mm diameter, 10mm long).

FAQ
What material are these screws made from?
Engineering-grade nylon (PA66 / Polyamide 66) — durable, lightweight, non-conductive, and corrosion-resistant.
Are nylon screws electrically insulating?
Yes. Nylon is a non-conductive material, making these screws ideal for PCB mounting, electrical enclosures, and any application where electrical isolation is required.
What screwdriver do I need?
A Phillips PH2 screwdriver. Apply moderate torque only — nylon screws have lower torque limits than metal and can strip if overtightened. Hand-tight plus a quarter turn is usually sufficient.
What is the thread size and compatibility?
M3 metric thread (3mm diameter). Compatible with M3 tapped holes, M3 hex nuts, and M3 threaded inserts. These are machine screws — they do not self-tap.
Can these be used outdoors?
Nylon is corrosion-resistant and moisture-resistant, suitable for light outdoor use. Prolonged UV exposure may cause gradual degradation — for long-term outdoor use, consider UV-stabilized nylon variants.
How do I read the size format?
Size is listed as M3 × [length]mm. For example, M3 × 10 means 3mm thread diameter and 10mm shaft length. The length is measured from under the head to the tip.
What pack sizes are available?
Available in packs of 10, 30, 50, 80, 100, 200, 300, and 500 pieces. Select your preferred quantity using the Pack Quantity option on the product page.
Do these require a nut or tapped hole?
Yes — these are machine screws, not self-tapping. They require a pre-tapped M3 hole, an M3 nut, or an M3 threaded insert to fasten correctly.
