Frequently asked questions
Which screws fit this standoff?
Both ends are M3 female threads, so use M3 machine screws. Choose a screw short enough that it does not bottom out inside the spacer.
How do I mount a board on a metal plate with this spacer?
Pass an M3 screw through the plate into one female end, then fix the PCB with a second M3 screw into the other end.
