Frequently asked questions
How do I mount a board with this standoff?
Screw the male end into the mounting surface or chassis. Place the board over the female end and fasten it with an M3 screw passing through the board's mounting hole.
Does it fit Arduino boards?
Many Arduino boards use 3.2 mm mounting holes that take M3 screws. Check the mounting hole diameter of your specific board before fitting.
