Hi,
I will need replacement screws for my FP3 very soon.
This post is helpful to pick the right size, but the screws you are showing do not have pre-applied threadlocker (the blue “glue” in the threads).
I think the threadlocker is important. It is used to prevent loosening of the screws due to vibrations (normal life vibrations, like having the FP in the door pocket of the car).
I think if we don’t pre-apply threadlocker we will risk having some loose screws after some time. That’s why selling official screws would be great, they would come in the proper size and with the proper products applied.
On the meantime, my best guess is that this product would work: Loctite Threadlocker 242. It’s blue and is used for screws that need to be disassembled eventually.
Beware: The product I’m suggesting is a best guess. I don’t know anything about electronics… We normally use this for big machines. Would be great to get Fairphone feedback here!
