I need the name of the screw for the HP quick deploy rail kit. The screw clicks into the square holes of the rack. It is a Gen4 Rail kit but the screw is like the Gen8 Rail kit ones. I called HP support, but they couldn't really help me. Unfortunately the rack manual does not name this screw either.
After googling a while, I found the compatible "Thumb Style Rack Screws". It would do the job but isn't exactly what I am looking for.
So, what is the name of the pictured screw.
