A machine screw is a type of screw designed to be used in pre-tapped holes or with nuts to fasten metal parts. It's like a more precise and versatile version of a wood screw, specifically for metal applications. Think of it as a tiny bolt that screws into a threaded hole. Unlike self-tapping screws, it needs a pre-existing thread to work correctly. It's essential for assembling electronics and other precision devices.
