Custom fastener shapes can be designed according to specific needs. Common fastener shapes include bolts, nuts, studs, screws, etc. Each shape has its specific application scenarios and design requirements.
Common fastener shapes and their application scenarios
Bolts: Bolts usually consist of a head and a cylindrical screw with an external thread, and the head is mostly hexagonal. Bolts need to be used in conjunction with nuts to fasten two parts with through holes. This type of connection is called bolt connection and is a detachable connection. Nut: A nut is a fastener with an internal threaded hole, usually in the shape of a flat hexagonal column, a flat square column, or a flat cylinder. Nuts need to be used in conjunction with bolts or studs to fasten two parts. Studs: Studs have no head, only a cylindrical screw with threads on both ends. When in use, one end is screwed into a part with an internal threaded hole, and the other end passes through a part with a through hole and screws on a nut to achieve a detachable connection.
Screw: The screw consists of a head and a screw rod. The head has various shapes to adapt to different assembly spaces and connection appearances. Screws can be divided into machine screws, set screws and special-purpose screws. Machine screws can directly act on parts with internal threaded holes to achieve fastening connections.
Washer: A washer is a flat circular ring fastener, mainly used to increase the contact surface area of the connected parts, reduce the pressure per unit area and protect the surface of the parts.
Rivet: The rivet consists of a head and a nail rod, which is used to firmly connect two parts with through holes. It is a non-detachable connection.
