I don’t know what type of screws does the acer nitro 5 need to connect to connect bottom panel to top panel of motherboard.

I can’t exactly answer your question but this guide shows you the screws: Acer Nitro 5 AN515-53-55G9 Wi-Fi Card Replacement 9mm length - just get a selection of metric screws in partitioned plastic box. Have you not got at least one original left over to measure or just compare in shop?
