This is very hard. It’s insanely hard to recognize the screws. If you have a diagram that shows where they go,you may be able to judge the shortest from medium sized. Any holes that have the silver ring attached to the logic board are HIGH RISK. If you use too long of a screw,there’s a good chance it will dig into the board and cause long screw damage. Its really a pain to organize mixed screws. You can look for diy information and see if it tells you which sizes go in which holes and use your best judgement,but know it’s risky if you mess up. I’m not exaggerating. Good luck!
