Machine screws are fasteners designed for use with a nut or threaded hole, offering precise and secure connections in various applications. They are typically fully threaded, conforming to the Unified Thread Standard for compatibility. Common head types include flat, pan, round, hex, and socket heads, while drive types include slotted, Phillips, Torx, and hex socket.
Materials used for machine screws range from steel (often coated for corrosion resistance) and stainless steel to brass and aluminum. Available in numerous sizes, they cater to diverse needs in electronics, machinery, furniture assembly, automotive, and construction.
Machine screws require pre-drilled and tapped holes and are tightened using the appropriate screwdriver or wrench. They are often paired with nuts and washers to distribute load and prevent material damage. Key advantages include precision, versatility, and reusability, making them essential in both industrial and everyday applications.
