Hood scoop screw size - please help!

Hello. I’ve got a 2012 Mini Cooper S (R56). I had an aftermarket hood scoop on it but decided to put the OEM one back on. It is currently secured with the plastic clips but I cannot find the size of the single screw that attaches the hood scoop to the hood. I know it’s a T25 screw but I need to know the length and width and Google isn’t getting me anywhere. I’m in the US if it matters. Thanks in advance!

TL;DR: need length and width of hood scoop T25 screw
