20mm PCB mounting spacer for project assemblies
This 20mm PCB spacer helps create a defined separation between a circuit board and a compatible mounting surface or another board. It can be considered for electronics enclosures, robotics builds and development-board projects where the mounting dimensions match.
Choose the spacer by the board’s mechanical requirements. The Arduino or Raspberry Pi name alone does not establish the hole size, clearance or fastener needed for a particular assembly.
Check the mechanical fit
- Listed length: 20mm.
- Mounting task: PCB spacing or standoff support.
- Thread: confirm size, pitch and whether threaded ends are provided.
- End configuration: confirm male/female, female/female or unthreaded design.
- Material and diameter: not established here.
Plan clearance and fasteners
Check clearance for solder joints, components, enclosure surfaces and connectors. Confirm how the 20mm measurement is defined on the supplied part, particularly if a threaded stud is present. Account for screw engagement without allowing a screw to reach circuitry.
The listing does not establish whether the spacer is nylon, brass or another metal. Do not assume electrical insulation from the word “spacer”; conductive hardware can still contact pads or traces if placed incorrectly.
Use appropriate washers and fasteners where required by your assembly. Do not overtighten or bend a PCB to force misaligned mounting holes into place. Quantity, screws and nuts are not established as included.
Browse robotic accessories at EPRO for other project hardware, matching dimensions before combining parts.
Frequently asked questions
Is it an M3 standoff?
An M3 thread is not established. Confirm the actual thread and bore.
Does it electrically insulate a PCB?
That depends on the material and installation. Insulating construction is not confirmed.
Will it fit every Arduino or Raspberry Pi?
No universal fit is established. Compare mounting-hole and clearance requirements for the exact board.
