So I somehow lost the screws for bottom casing on my late 2016 macbook pro. Does anyone know what kind of screws it uses/where I can purchase them? Thanks!

Did you try going to the Apple Store? You should be able to get them replaced for free if they fell out on their own (one or two). If you popped the bottom off to look around and misplaced them thats a bigger problem ;-{ So far I haven’t seen any parts available yet as the system is so new - Sorry
