M2–M4 Black & White Nylon Plastic Phillips Pan Round Head Screw Bolt 5–50mm

Nylon plastic Phillips pan head screws are the go-to fastener wherever electrical isolation, non-magnetic properties, or lightweight construction is required. Available in M2, M2.5, M3, and M4 in lengths from 5mm to 50mm, in both black and white nylon (PA66), these screws are essential for PCB standoff mounting, sensor brackets, and any assembly where a metal screw would create a short circuit or interference.

Why Choose Nylon Plastic Screws?

Electrically non-conductive — PA66 nylon is a dielectric material; eliminates risk of short circuits between PCB traces and fastener
Non-magnetic — no magnetic interference; essential for sensors, RF circuits, and precision instruments
Lightweight — density ~1.14 g/cm³ vs 7.9 g/cm³ for steel; significant weight saving in drone, robotics, and portable device builds
Chemical resistance — resistant to oils, fuels, and many solvents; suitable for automotive sensor brackets and industrial environments
Black & white options — black for electronics and dark builds; white for medical devices, food equipment, and clean-room applications

Typical Applications

PCB standoff mounting and board-to-board spacing in electronics enclosures
Sensor bracket mounting where electrical isolation from chassis is required

Frequently Asked Questions

Q: Are nylon screws strong enough for PCB mounting?: A: Yes. PA66 nylon has a tensile strength of approximately 80 MPa, which is more than sufficient for PCB standoff mounting, sensor brackets, and light mechanical assembly. Do not use nylon screws in high-load structural applications or where temperatures exceed 120°C continuously.
Q: What is the maximum temperature for nylon screws?: A: PA66 nylon has a continuous service temperature of approximately 100–120°C and a short-term peak of 150°C. For higher temperature applications (e.g., near power components), use PEEK or stainless steel screws instead.
Q: Can I use nylon screws outdoors?: A: PA66 nylon has moderate UV resistance. For prolonged outdoor exposure, black nylon (carbon black UV stabiliser) performs better than white. For long-term outdoor structural use, consider UV-stabilised nylon or stainless steel alternatives.
