Nylon Hex Standoff M3×6mm Female-Female PCB Spacer 10-Pack

Nylon Hex Standoff M3×6mm — Female-Female PCB Spacer, 10-Pack

M3×6mm nylon hex female-female standoffs are the standard PCB spacer for mounting circuit boards at a fixed height above a base panel or between two PCBs, while providing complete electrical isolation between the board and the mounting surface. The non-conductive nylon (PA66) construction eliminates the risk of short circuits between PCB traces and the standoff, making these essential for electronics enclosure assembly, Raspberry Pi mounting, and Arduino shield stacking.

Key Specifications

Why Choose Nylon Hex Standoffs?

• Electrically non-conductive — PA66 nylon is a dielectric material; eliminates risk of short circuits between PCB traces and standoff body
• Non-magnetic — no magnetic interference; essential for RF circuits, sensors, and precision instruments
• Lightweight — density ~1.14 g/cm³ vs 8.5 g/cm³ for brass; significant weight saving in drone, robotics, and portable device builds
• Female-female configuration — both ends accept M3 screws; mount to base panel with one screw, attach PCB with another
• 6mm height — standard PCB clearance height; provides sufficient space for through-hole component leads and solder joints on the underside of the PCB

Typical Applications

• Raspberry Pi 3/4/5 mounting in electronics enclosures and custom cases
• Arduino Uno, Mega, and shield stacking (M3 mounting holes)
• PCB-to-panel mounting in electronics enclosures (6mm clearance for solder joints)
• Single-board computer (SBC) mounting: Orange Pi, Rock Pi, Banana Pi
• Sensor board and module mounting requiring electrical isolation
• 3D printer control board mounting (SKR, BTT, Duet boards)

Frequently Asked Questions

Q: What is the difference between female-female and male-female standoffs?

A: Female-female (F-F) standoffs have tapped holes at both ends and require a screw at each end to mount. Male-female (M-F) standoffs have a threaded stud at one end and a tapped hole at the other; the stud threads directly into a tapped hole or nut, while the female end accepts a screw. F-F standoffs are more common for PCB mounting where screws are used at both ends.

Q: Why use nylon standoffs instead of brass for PCB mounting?

A: Nylon standoffs provide electrical isolation between the PCB and the mounting surface, eliminating the risk of short circuits. Brass standoffs are electrically conductive and can cause shorts if they contact PCB traces or pads. Use nylon for electrical isolation; use brass when electrical grounding of the PCB to the chassis is required.

Q: Can I stack multiple nylon standoffs to get a greater height?

A: Yes. Female-female standoffs can be stacked by threading an M3 screw through one standoff into the next. However, stacking reduces rigidity. For heights greater than 20mm, consider using a single longer standoff instead of stacking multiple short ones.
