Stripped Screw Threading
 

Does anyone know how to remove a screw that is stripped in the threading of the bolt, not the head? Every other thread i checked on stripped screws is about the head of the bolt being stripped..

If the threads are stripped, grab it with some pliers or anything you can use to grab it, and just pull it out

I've tried that, it just won't budge..maybe if i keep turning the screw to damage the threads more, it will come out easier? To make things worse, the gun i'm working on is a Classic Army P90, which only requires 2 screws to be removed to access the mechbox and one of them is the stripped one :(
