I Lost a Screws

You have to be careful which screw you put in which hole. They have different lengths and if you put in the wrong one and tighten it and can damage the motherboard. You need to buy the pack of screws and find a video or an article that tells you the length and size of the screw. I haven't found one yet. If you can borrow a iPhone 5 from someone and compare the screws. I was looking for screws the other day because I was changing the screen on iPhone xs max and someone didn't put the cover and screws in for the screen and battery. I found the cover and had it sent from China but I couldn't find the screws and bought them for an iPhone X and will have to figure out which screws will work. I hope this helps you.
