Fasteners are a wide range of mechanical parts used for fastening connections. They are used in a broad range of industries, including energy, electronics, electrical appliances, machinery, chemicals, metallurgy, mold making, and hydraulics. Various types of fasteners can be found on all kinds of machinery, equipment, vehicles, ships, railways, bridges, buildings, structures, tools, instruments, chemicals, meters, and supplies, making them the most widely used basic mechanical components.
Fasteners are characterized by a wide variety of specifications, diverse performance and applications, and a high degree of standardization, serialization, and generalization. Therefore, some people refer to fasteners with existing national standards as standard fasteners, or simply standard parts.
Fasteners are a general term for a class of mechanical parts used to fasten two or more parts (or components) together to form a single unit.
