Nylon Hex Standoff M3×8mm Female-Female PCB Spacer 10-Pack

Nylon Hex Standoff M3×8mm — Female-Female PCB Spacer, 10-Pack

M3×8mm nylon hex female-female standoffs provide 8mm of PCB clearance height — 2mm more than the standard 6mm standoff — for applications where taller through-hole components, connectors, or Raspberry Pi HAT stacking require additional clearance between the PCB and the mounting surface. The non-conductive nylon construction provides complete electrical isolation.

Key Specifications

Why Choose 8mm Nylon Standoffs?

• 8mm clearance for taller components — 2mm more than standard 6mm; accommodates taller through-hole components, electrolytic capacitors, and connectors on the underside of the PCB
• Raspberry Pi HAT stacking — 8mm is the standard standoff height for stacking Raspberry Pi HATs (add-on boards) above the main Pi board
• Electrically non-conductive — PA66 nylon eliminates short circuit risk between PCB traces and standoff body
• Female-female configuration — both ends accept M3 screws for flexible mounting
• Lightweight — nylon construction for weight-critical drone and portable device builds

Typical Applications

• Raspberry Pi HAT stacking (8mm standard HAT standoff height)
• PCB mounting with taller through-hole components requiring extra clearance
• Arduino shield stacking with taller components
• Electronics enclosure PCB mounting where 6mm is insufficient
• Sensor board and module mounting with connector clearance
• 3D printer control board mounting with cable connector clearance

Compatible With

• M3 machine screws (Phillips pan head, hex socket cap head)
• M3 hex nuts and nyloc nuts
• Raspberry Pi 3/4/5 HAT mounting (M3 holes, 8mm standoff standard)
• PCB mounting holes: standard 3.2mm clearance drill
• Can be combined with M3×6mm standoffs for custom heights

Package Contents

• 10× M3×8mm nylon hex female-female standoffs

Frequently Asked Questions

Q: What is the standard standoff height for Raspberry Pi HAT stacking?

A: The Raspberry Pi HAT specification recommends 8mm standoffs for stacking HATs above the main Pi board. This provides clearance for the 40-pin GPIO header (8.5mm tall) and allows the HAT to sit correctly above the connector. M3×8mm nylon standoffs are the standard choice for this application.

Q: When should I use 8mm standoffs instead of 6mm?

A: Use 8mm standoffs when: (1) stacking Raspberry Pi HATs, (2) the PCB has tall through-hole components (electrolytic capacitors, large connectors) on the underside that need more than 6mm clearance, or (3) you need additional space for cable routing under the PCB.

Q: Can I mix 6mm and 8mm standoffs in the same assembly?

A: No. All four standoffs in a PCB mounting assembly must be the same height to keep the PCB level. Mixing heights will tilt the PCB and stress the mounting holes. If you need a height between 6mm and 8mm, use 6mm standoffs with a 2mm spacer washer.
