A hex nut is a type of fastener that has a hexagonal (six-sided) shape. It is used in conjunction with a bolt or screw to secure two or more parts together. Hex nuts are often used in construction and manufacturing, as well as in a wide variety of other applications. They are available in a variety of materials, including steel, stainless steel, brass, and nylon, and come in various sizes to suit different applications. To install a hex nut, the bolt or screw is inserted through a hole in the parts being joined, and the nut is tightened down onto the bolt or screw using a tool such as a wrench or socket.
