FAQ

Q: What is the thread pitch for M3?
A: M3 standard metric thread has a pitch of 0.5mm. This is the most common thread size for PC case panels, fan mounts, and expansion slot covers.

Q: Can I use a screwdriver with these?
A: Yes. The head has both a slotted groove and a Phillips cross recess, so you can use a flat-head or PH2 Phillips screwdriver in addition to hand tightening.

Q: What is the difference between 4.5mm and 12mm lengths?
A: 4.5–6mm lengths are ideal for thin panel mounts (side panels, slot covers). 8–12mm lengths suit thicker brackets, fan mounts, or applications requiring more thread engagement.
