M2 x 20mm Male to Female Nylon Hexagonal Spacer Standoff

Specifications:

• Thread Size: M2 (Metric 2mm)
• Body Height: 20mm (Excluding male thread) 
• Material: High-Strength Nylon 
• Male Thread Length: Approx 6mm
• Type: Male to Female (M-F Standoff) 
• Shape: Hexagonal (Easy tool grip)
• Insulation: Fully Non-conductive

Key Applications:

• FPV Drone Stacks: Mounting 20x20mm flight controllers with high clearance for airflow.
• IoT Sensor Towers: Creating vertical stacks of environmental sensors in compact weather stations.
• Custom Enclosures: Providing deep offsets for PCBs inside deep waterproof or 3D-printed cases.

Project Evolution

• Past Projects: If you've used standard standoffs, you know they require extra screws; M-F variants simplify the entire build.
• Feature Upgrade: The Male-to-Female design allows for "infinite" stacking possibilities in a smaller footprint.
• Effort Level: Intermediate. Requires M2 threaded holes or M2 nuts for the base.

Virtual Technician & Wiring 

• Safety Warning: Hand-tighten only. Over-torquing can lead to the male thread snapping or the internal thread stripping.
• Mounting Guide: Screw the male end into your base, stack your PCB, then screw the male end of the next spacer through the PCB and into the first.

Frequently Asked Questions (FAQ) 

1. What does Male-to-Female mean?
   It has an external screw thread on one side and an internal threaded hole on the other.
2. Can I screw two of these together?
   Yes, the male end of one fits into the female end of another.
3. Is the 20mm length including the male thread?
   No, 20mm is the length of the hexagonal body only.
4. What is the thread pitch?
   Standard M2 metric pitch (0.4mm).
5. Is nylon better than metal for drones?
   Yes, it is much lighter and provides vibration dampening.
6. Are these anti-static?
   Yes, Nylon 66 is a natural insulator.
7. What tool should I use?
   A 5.5mm hex socket or needle-nose pliers.
8. Can I use these with M2.5 holes?
   They fit the hole, but M2.5 screws will not thread into them.
9. Will the male thread break easily?
   Under normal hand-tightening, it is very durable.
10. How many can I stack?
    Theoretically as many as needed; 3-4 is common for stability.
11. Are they RoHS compliant?
    Yes.
12. What is the color?
    Typically White/Natural or Black.
13. Do these melt near heat sinks?
    Keep away from components exceeding 85°C.
14. Is it logic-safe?
    Yes, no risk of short circuits.
15. Can I use them for PC motherboards?
    No, PCs typically use M3 or 6-32 threads.
16. How do I remove a snapped thread?
    It can usually be carefully drilled out or removed with a hot pin.
17. Are they magnetic?
    No, nylon is non-magnetic.
18. Can I use them in water?
    Yes, they are water-resistant.
19. What is the weight?
    Approx 0.2g per piece.
20. Is there a bulk pack?
    Yes, contact Probots for 100+ unit pricing.
