M3 Black Hexagonal Nylon Nut

Specifications:

• Thread Size: M2 (2mm Metric)
• Thread Pitch: 0.5mm (Standard)
• Material: Nylon (Polyamide)
• Color: Industrial Black
• Width Across Flats: 5.5mm
• Height/Thickness: 2.4mm

Key Applications:

• FPV Micro-Drones: Securing flight controllers and VTX modules without adding weight.
• Camera Mounts: Perfect for mounting ESP32-CAM or Raspberry Pi Camera modules to plastic brackets.
• Wearable Tech: Lightweight fastening for sensors in clothing-integrated electronics.
• Medical Prototypes: Non-magnetic and non-reactive fastening for sensitive diagnostic tools.
• Compact Robotics: Ideal for the small-scale 10mm and 20mm chassis builds.

Project Evolution

• Past Projects (Prerequisites): If you've previously used metal nuts on PCB standoffs, you've likely worried about the nut edge touching a nearby trace.
• Feature Upgrade: Switching to this Nylon-Native fastening system unlocks "Safety-First" design. You can now place mounting holes closer to active components, allowing for more compact PCB layouts and denser hardware stacking.
• Effort/Requirements: Beginner. Fully compatible with all standard M3 screws and spacers.

Virtual Technician & Wiring 

• Isolation: 100% non-conductive; no nylon washers required for insulation.
• Torque: Avoid impact drivers. Manual tightening is best for nylon-on-nylon or nylon-on-metal threading.

Frequently Asked Questions (FAQ) 

1. What is the thread size?
   Standard M3 (3mm).
2. Will these fit a 5.5mm wrench?
   Yes, the width across flats is 5.5mm.
3. Are they conductive?
   No, they are made of insulating Nylon 66.
4. Can I use them with metal M3 screws?
   Yes, they are fully compatible.
5. How much weight do they add?
   Negligible; approximately 0.1g per nut.
6. Are they resistant to rust?
   Yes, nylon is 100% rust and corrosion-proof.
7. What is the thread pitch?
   0.5mm.
8. Can I use these for outdoor sensors?
   Yes, black nylon has excellent UV and weather resistance.
9. What is the maximum temperature?
   120°C.
10. Are they RoHS compliant?
    Yes.
11. Do I need a locking washer?
    Nylon has a natural "grip" that resists vibration better than metal.
12. Can I use them in a vacuum?
    Yes, Nylon 66 has low outgassing properties.
13. Will they melt near a hot motor?
    They are safe up to 120°C; check your motor's surface temp first.
14. How thick are these nuts?
    Approximately 2.4mm.
15. Are they magnetic?
    No, 100% non-magnetic.
16. Can I dye them?
    Not recommended; it can weaken the plastic.
17. What is the dielectric strength?
    50 kV/mm.
18. Are they brittle?
    No, Nylon 66 is chosen for its high impact toughness.
19. How many pieces are in a pack?
    This listing is for 10 pieces.
20. How are they shipped?
    Via Probots™ Secure-Transit  to prevent damage.
