[SOLVED] GPU 'fastener' screw size

[Exploding PSU]

Quick question, I'm disassembling my GPU right now, due to, reasons.. But I can't unscrew the four screws for the 'fastener' thing (the 4 screws that hold the PCB to the heatsink). My smallest screwdriver is just too big to fit the screw. What screwdriver size do I need for those screws? For the recod, the smallest I have is a philips #00 and that one was able to disassemble the entire thing (including the fans and LEDs) except those four last screws..
Just asking before I make the trip to the hardware store for the new screwdriver.

Guess you could try a #000. Don't think it is a standard size for that type of screws and that they vary from manufacturer to manufacturer of the card.

Edit; Grab a #0000 at the same time to be sure.

Might even be torq-headed screws like those on HDD casing -- check with magnifying glass.
