gépcsavar

A gépcsavar, often translated as machine screw, is a type of fastener used to join materials together. It is characterized by its threads, which are designed to engage with a pre-tapped hole or a nut. Machine screws are typically used in applications where a strong and secure connection is required, and they are often employed in mechanical assemblies, electronics, and machinery.

The head of a machine screw can come in various forms, including flat head, pan head, round head, and hex head, each suited for different mounting and clearance requirements. The shaft of the screw is threaded along its entire length or a portion of it. The thread pitch, which is the distance between adjacent threads, is also a critical specification that determines how the screw will engage with its mating part.

Machine screws are usually made from materials like steel, stainless steel, brass, or aluminum, chosen based on the desired strength, corrosion resistance, and conductivity. They are tightened using a screwdriver or a wrench, depending on the type of head. Unlike wood screws, machine screws do not typically cut their own threads; they rely on a pre-existing threaded hole or a nut for engagement. This makes them suitable for repeated assembly and disassembly without damaging the material. The precise threading and consistent manufacturing of machine screws are essential for their reliable performance in a wide range of engineering applications.
