There are studs, washers, threaded rods, screws, etc. Each type of fastener has its own advantages and application requirements. Carbon steel screws can be used without nuts. It can be driven with a screwdriver.
Carbon steel studs are used to hold two components together in tight spaces. Carbon steel materials have poor ductility but high hardness. This allows carbon steel to be used in applications that require high hardness, such as carbon steel studs in the oil and gas industry and in power transmission lines.
Fasteners vary in size, shape, grade and specification. The most commonly used fasteners are bolts and nuts. Carbon steel washers are also commonly used to tightly mate nuts with bolt heads and mating surfaces.
