Lost tiny screw from inside printhead

Can anyone help me? I seem to have lost the tiny screw that holds the nozzle in place inside my Snapmaker 2 printhead. Can anyone tell me the size and if there’s any chance I can find a replacement?

From this chart it has to be a M3 screw (because of H2.0 screwdriver/Allen wrench):


I guess it’s about 4mm long but I am on vacation now.

If you can’t find anything in your local hardware store you could also reach out to support@snapmaker.com or open a ticket

Oh that’s great thanks very much, I’ve now found another post with a similar problem and it looks like it could be a 4mm grub screw, so I think you’re right about the size, thank you for your help.

There are a lot of grub screw sets on Amazon and Ali for M2-M4. It’s always worth having something like this.

Ah ok thanks, I’ll get some now!
