Fasteners are typically small hardware pieces such as washers, screws, studs fasteners and more. Fasteners are used in several different industries including aerospace. One of the oldest and most common fasteners on the market is the nail. The standard nail is made of a shank, or a metal rod, and is flat at the top with an end that is pointed. Nails are typically hammered into wood, drywall, etc. and are used to fasten materials together. The standard nail is made from steel, but other variations include aluminum, brass, bronze, iron, or copper. The United States alone has over 300 different types of nails manufactured, most of which are used in residential construction.
