hey I have a stigma hyper v2, which was shorting out and a little rattly. I opened it up to find the two screws that hold the lid on were totally stripped. Upon trying to put it back together I found that the screw just wouldnt catch. Im pretty sure its not the screws so much as it is the female side.

So here is my question. I cant just get new screws so I need to rethead something. Right? What would you do? Can I just get a bigger screw or an american threading and jam it in there? Is there some kind of tiny tap I can use.
