Nylon M3×6mm Phillips Pan Head Screw Non-Conductive 20-Pack

Nylon M3×6mm Phillips Pan Head Screw — Non-Conductive, 20-Pack

M3×6mm nylon Phillips pan head screws are the standard non-conductive fastener for PCB mounting, sensor bracket assembly, and any electronics application where a metal screw would create a short circuit, magnetic interference, or galvanic corrosion. The PA66 nylon construction is electrically non-conductive, non-magnetic, and lightweight — making these screws essential for RF-sensitive circuits, precision sensors, and weight-critical drone and robotics builds.

Why Choose Nylon Screws for Electronics?

• Electrically non-conductive — PA66 nylon is a dielectric material; eliminates risk of short circuits between PCB traces and screw body; essential where metal screws would contact live traces
• Non-magnetic — no magnetic interference; critical for magnetometers, compasses, Hall effect sensors, and RF circuits where metal screws would affect readings
• Lightweight — density ~1.14 g/cm³ vs 7.9 g/cm³ for steel; significant weight saving in drone, UAV, and portable device builds
• No galvanic corrosion — nylon does not react with aluminium, copper, or other metals; prevents galvanic corrosion in mixed-metal assemblies
• M3×6mm standard length — the most common M3 length for PCB standoff mounting and electronics enclosure assembly

Typical Applications

• PCB mounting to nylon standoffs in electronics enclosures (electrical isolation)
• Magnetometer and compass module mounting on drones and robots (non-magnetic)
• RF circuit board mounting where metal screws would affect antenna performance
• Sensor bracket mounting requiring electrical isolation from chassis
• Raspberry Pi and SBC mounting in metal enclosures (isolation from chassis)
• 3D printer control board mounting (isolation from aluminium frame)

Compatible With

• M3 nylon standoffs (M3×6mm, M3×8mm female-female)
• M3 nylon hex nuts
• M3 brass standoffs (nylon screw for electrical isolation)
• PCB mounting holes: standard 3.2mm clearance drill
• Phillips #1 screwdriver; do not overtighten — nylon threads strip more easily than metal

Package Contents

• 20× M3×6mm nylon Phillips pan head screws

Frequently Asked Questions

Q: How tight should I tighten nylon screws?

A: Nylon screws should be tightened finger-tight plus approximately 1/4 turn with a screwdriver. Do not overtighten — nylon threads have lower shear strength than metal and will strip if over-torqued. The recommended torque for M3 nylon screws is approximately 0.3–0.5 Nm.

Q: Can nylon screws be used outdoors?

A: PA66 nylon has moderate UV resistance. Black nylon (carbon black UV stabiliser) performs better than natural (white) nylon for outdoor exposure. For long-term outdoor structural use, consider UV-stabilised nylon or stainless steel alternatives.

Q: Why use nylon screws instead of stainless steel for PCB mounting?

A: Stainless steel screws are electrically conductive and can cause short circuits if they contact PCB traces or pads. They are also magnetic (some grades) and can interfere with sensors. Nylon screws eliminate both risks. Use stainless steel when structural strength is required; use nylon when electrical isolation or non-magnetic properties are needed.
