What screw driver size do PS2 controllers use?

My PS2 controller analog stick is getting stuck when pushed down, so I am going to clean out the controller to see if that helps fix it any, however, my smallest screw driver seems too small, and I can't find any infomation for it online, I'm assuming PH00, but would prefer to know before going out and buying one.

Thanks
Matt

 

^^ web searches turn up zilch in what i can describe...
the screwdriver is a posidrive (phillips) large glasses screwdriver.
screwdriver tip is roughly 1/5 mm in width and the same in depth. (even dimensions)
any good jewelry screwdriver set or a console tool kit will have what you need!

all the best! :friendly_wink:

How to repair / fix a broken playstation (2) controller

 

I think PH1 is the correct size as its seems to fit perfectly. PH00 would probably be too small. I have used a PH0 before though but its a little loose.

 

Thanks, I'll order a PH1 and see how it goes, much prefer to save a controller than open a new one.

 

Always found DS2 a pain in the ass to put back together. Sounds like they just need a clean though, so good luck!
