Pentalobe 1.5 Screws and driver

My son purchased a replacement screen for his macbook pro A1707 and of our his dad, me, has to replace the screen since I am a retired Network Administrator...Well I an NEW to macbook pros like these so I have a question or two I need help on. With the replacement screen they sent some cheap bits, it wasn't from ifixit but some 3rd party company somewhere I don't recall where he got it from. Of course they send a 0.8 torx bit instead of a P2 Pentalobe driver which I ordered earlier. My question is where can I purchase the screws from Step 23 on ifixit website for 2017 Mackbook Pro with touchbar and retina A1707..

they are the P2 1.5mm that's on the wifi bar. I rather REPLACE those particular screws instead of reusing them. I don't trust those small screws like that. So do you know where I can purchase those screws from? I cannot find them things anywhere. Thank you in advance, Rob
