Accu are fantastic. They also have European sites and maybe more? Always my goto if we need weird screws and they will also make to order if you need something

Accu are fantastic. They also have European sites and maybe more? Always my goto if we need weird screws and they will also make to order if you need something special. Edit : I would guess McMaster fills this role in the US, so it's nice to have an alternative here. Also they have a lot of non-standard lengths and things like tiny M2s or even smaller. We used them all the time for machine vision products (cameras often use M2 frame mounts, lenses with itty bitty grub screws).
