Frequently asked questions
Will it work with a standard M3 PCB spacer?
Yes, an M3 bolt of this length suits M3 threaded spacers. Check the total stack of board, spacer and nut so the bolt does not bottom out before the board is clamped.
Which screwdriver should I use?
Use a Phillips (cross) screwdriver that fits the recess fully, usually PH1 for M3 screws. A loose-fitting tip can damage the head.
