I'm trying to get the bounces and rattles out of my dash and have started taking it apart. It's mostly held together with screws just like this and there are a bunch missing. I've tried the hardware store and some auto parts stores but no one has a screw with this same skinny shaft and coarse thread. I looked on Quadratec and didn't see anything like this. The hex heads take a 1/4" socket (7mm is too large, 6mm is too small).
