Decimo

hello i recently bought the thermaltake pacific c360 soft tube kit and when i went to assemble in my case i realized that it didnt bring the 12 required screws for the radiator fans, im hesistant on buying some m3 screws i keep reading about because i tried using some extra screws i had from an aio and it was stripping the mounting hole and the last thing i wanna do is mess it up, i just want to know the exact kind of screws i need so i can buy them
