Riing quad case fans screws

[Psycrow]

I bought the riing quad 140 mm case fans but one of the fans would not let me tighten all the screws since i had to install it and the screw hole got expandet..
Is there any better or thicker case fan screws to fix this ?

The fan is installed and sticks to the case, but i would rather have to tighten en, so it dont come loose.
