Hardware standard parts are standard parts made of metal. The following is the concept and classification of common hardware standard parts.
1. A type of fastener consisting of a head and a screw (cylindrical body with an external thread) in two parts, which needs to cooperate with a nut and is used to fasten two parts with through holes. This type of connection is called a bolted connection. If the nut is unscrewed from the bolt, the two parts can be separated, so the bolt connection is a detachable connection.
2. There is no head on the stud, only a type of fastener with both ends being externally threaded. When connected, one end must be screwed into a part with an internally threaded hole and the other end through a part with a through hole, and then screw on the nut, even if the two parts are fastened together in one piece. This type of connection is called a stud connection and it is also a detachable connection. It is mainly used for occasions when one of the connected parts has a large thickness, requires a compact structure, or is frequently used for bolting because of frequent disassembly.
3. Screws are also a type of fastener consisting of a head and a screw. They can be divided into three categories according to their purpose: Machine screws, set screws, and special-purpose screws. The machine screw is mainly used for a part with a tight threaded hole, and a fastening connection with a part with a through hole, and does not require a nut to fit (this type of connection is called a screw connection and is also a detachable connection; it can also be Fits with a nut for fastening connections between two parts with through holes.) Set screws are used to fix the relative position between two parts. Special-purpose screws such as eyebolts are used for lifting parts.
4. Nuts have internal threaded holes. The shape is generally flat hexagonal, cylindrical or flat cylindrical, with bolts, studs or machine screws, used to fasten and connect two parts. Become a whole.
5. Self-tapping screws are similar to machine screws, but the thread on the screw is a special thread for self-tapping screws. It is used to fasten and connect two thin metal components into a single piece. The small holes need to be made in advance on the components. Because the screws have a high hardness, they can be screwed directly into the holes of the components to make the components Form the corresponding internal thread. This type of connection is also a detachable connection.
6, wood screws and machine screws are similar, but the thread on the screw is a special wood screw thread, can be directly screwed into the wood components (or parts), used to put a metal (or non-metallic) parts with holes Fastened together with a wooden member. This connection is also a detachable connection.
7. The washer is in the shape of a flat circular ring type fastener. Placed between the supporting surface of the bolt, screw or nut and the surface of the connecting part, play the role of increasing the contact surface area of ​​the connected parts, reducing the pressure per unit area and protecting the surface of the connected parts from being damaged; another type of elastic gasket, Can also play a role in preventing the nut from loosening.
8. The retaining ring is installed in the shaft groove or hole groove of the machine or equipment and plays the role of blocking the left and right movement of the parts on the shaft or hole.
9. The pins are mainly used for positioning of parts, and some are also used for connecting parts, fixing parts, transmitting power or locking other fasteners.
10. Rivets A type of fastener consisting of two parts, the head and the shank, used to fasten the parts (or components) that connect the two through-holes to make it a unitary body. This type of connection is called rivet connection, or simply riveting. Non-detachable connection. Because the two parts that are connected together must be separated, the rivet on the part must be destroyed.
11. Assemblies and connection subassemblies refer to a combination of supplied fasteners, such as a machine screw (or bolts, self-supply screws) and flat washers (or spring washers, lock washers) combined supply; Refers to a kind of special bolts, nuts and washers to provide a combination of fasteners, such as steel structure with high-strength large hex head bolts.
12. Welded nails Heterogeneous fasteners consisting of a shank and a nail head (or without a nail head), which are fixedly attached to a part (or component) by welding so that they can be connected to other parts.
