Amazon

something like this https://www.amazon.com/SGTKJSJS-M-2-Screw-NVMe-Mounting/dp/B07Q3DLCJ4/ref=sr_1_3?dchild=1&keywords=M.2+SCREWS&qid=1630423219&sr=8-3

No M.2 drive comes with the screw. It comes with the motherboard. If you saved the spare parts for the motherboard it should be in those.

Nevermind that’s a laptop

You can buy replacement M.2 screws from Amazon. If you don't have the option to use Amazon just search on whatever store you can use.

I found this one just doing a quick search: https://www.amazon.com/SGTKJSJS-M-2-Screw-NVMe-Mounting/dp/B07Q3DLCJ4/ref=sr_1_3?crid=3LYC784LTUB42&keywords=m.2+ssd+screw&qid=1650813175&sprefix=m.2+ssd+screw%2Caps%2C57&sr=8-3

Edit: I am assuming that is an asus motherboard. The pattern looks the same as my TUF B550.
