What is a machine screw?

A machine screw is a type of fastener with a threaded shank and a blunt end designed to be threaded into a tapped hole or used with a nut. They are typically made of steel, stainless steel, or brass and are available in a variety of sizes and thread types. The thread pitch and diameter of a machine screw determine the strength and holding capacity. Machine screws are commonly used in machinery, electronic devices, and other precision applications where tight connections are necessary. They are often distinguished from other types of screws by their small size and their ability to be tightened by a screwdriver or wrench.
