A machine screw is used for holding parts together in different machines: engines, electronic, or manufacturing equipment. A machine screw is typically installed by inserting it into pre existing holes unlike the other screws that can cut through a surface as they’re installed. A machine screw is not threaded all the way down. Also this screw is normally used for metal to metal attachments. 

Generally, screws don’t need nuts to get fastened. They become secure by being tightened into the hole using a screwdriver. Screws are usually shorter than the width of the material being screwed and don’t protrude on to the other side.

Sockets are gears for attaching a turning tool to lock fasteners. They fit over the head of the fastener to provide torque. Fasteners such as socket screws, also known as Allen Head screws, have sockets within their heads so that Allen wrench could secure the screw.
