Lost screws from iphone 5c?

So I had recently cracked my screen and I can't use my phone. I ordered a new screen online and I was so excited I tried to fix it myself (I'm an idiot) and I took out the bottom screws on the outside of the charging port bellow the home button and ended up losing them because they're so tiny 😟 I was wondering if apple happened to sell them or if I should just buy them online? or if they're even completely necessary for my phone to still work
