Frequently asked questions
Which bolt does this nut fit?
It is intended for M3 bolts, such as M3x16 mm cross-head bolts. Make sure the bolt diameter and thread pitch match the M3 standard.
Can I use it with PCB spacers?
Yes, M3 nuts are used to lock M3 bolts that pass through a board and into a spacer. Tighten gently to avoid stripping the thread or cracking plastic parts.
