A flat head screw is a type of fastener characterized by a flat, countersunk head that allows it to sit flush with the surface of the material it is driven into. This design is commonly used in woodworking and metalworking, providing a clean finish and preventing snagging on surfaces. The screw is typically driven in using a screwdriver, with various drive types available, such as Phillips or slotted. Flat head screws are often made from materials like steel, stainless steel, or brass, depending on the application and required strength. They are widely used in construction, furniture assembly, and machinery, making them essential components in many industries. Their ability to blend seamlessly into surfaces makes them a popular choice for aesthetic purposes as well.
