Overview

Product Overview

M3 hexagon copper pillar screw kit is a 120-piece standoff and screw set for mounting PCBs, stacking boards, and creating secure spacing inside electronics builds. Designed for makers, repair work, and prototyping, these M3 threaded hex spacers help fasten controller boards, sensor modules, cases, and panels in projects using Arduino, Raspberry Pi, ESP32, robotics, and DIY enclosures. The included plastic storage box keeps the assorted hardware organized for bench use, making this a practical choice for PCB assembly, motherboard spacing, instrument panels, and general electronics hardware needs.

Questions & answers

Frequently asked questions

It works with Arduino, Raspberry Pi, ESP32, and other electronics builds when the board, case, or panel uses M3 mounting holes. Check your board’s mounting-hole diameter and layout before ordering, because hardware size is project-specific.
Yes. The kit includes assorted M3 standoffs and screws in a plastic storage box, so the hardware is organized for bench use. No soldering is required; select the needed M3 parts and fasten them mechanically.
These are M3 threaded hex copper pillars with matching screw hardware for mechanical mounting, not a signal interface. Because the standoffs are metal, avoid contact with exposed traces or pads unless your PCB design allows it.
Use the spacers to mount PCBs, stack boards, secure controller modules, or create clearance inside DIY enclosures. They are useful for robotics builds, instrument panels, sensor assemblies, and general electronics repair or prototyping work.
Do not force the screws if the holes feel too tight or misaligned. Confirm the project uses M3 hardware, align the standoff squarely, and switch to the correct size hardware if your board or enclosure uses a different thread.
