A: A shoulder screw seems the appropriate fastener if I understand the situation. These have a threaded portion at the end of the shaft and an unthreaded portion beneath the head. The shoulder is formed at the border between the two portions, the unthreaded area being of greater diameter than the threaded. This shoulder allows the screw to be secured in the camera before it bottoms out in the hole. Please try a search for 'shoulder screws' to understand the variety of configurations or visit a good hardware store. The standard 1/4-20 threading applies.
