About Pan Machine Screws:
Pan head machine screws are machine screws with heads that are flat on top and rounded on the sides. They're similar to oval head machine screws, which also have rounded sides; the difference is that oval head screws have a rounded top, too, as opposed to a flat top, and they have tapered bases. Both are commonly used for metal applications.
