I've got a Bullet Stratocaster and I took the pickups out to shield the covers, as they were a bit noisy. In the process I accidenaly dropped a screw into the air vents on the floor. Does anyone know what types of screw I can get at the hardware store that will easily replace it? I don't care how the screw looks or if it's countersunl, I just care that the threads fit the pickup.
