I got a Corsair 5000D airflow case from a friend for free but it is missing all the four screws that hold the side panels on the back. All the screws I can find on the internet are the short version that don’t have enough reach.
This screw is from my own PC case.
Edit: image with the short version that I was talking about
“thumbscrew” is the search term you are looking for. 6-32 sounds right. https://a.co/d/9AvShgu
I know they are thumbscrews but all of the ones I find are too short, these look small on other images so I don’t want to order then return a bunch
