Fasteners are a class of mechanical parts that are used for fastening connections and are widely used. Fasteners, the use of a wide range of industries, including energy, electronics, electrical, mechanical, chemical, metallurgical, mold, hydraulic and other industries, in a variety of machinery, equipment, vehicles, ships, railroads, bridges, buildings, structures, tools, instruments, chemicals, instruments and supplies, etc., can see a variety of fasteners, is the most widely used mechanical foundation parts. It is characterized by a wide variety of specifications, different performance uses, and standardization, serialization, generalization of the degree is also extremely high. Therefore, some people also have a national standard for a class of fasteners called standard fasteners, or simply referred to as standard parts.
A fastener is an indispensable connecting element in mechanical engineering, primarily used to join and secure two or more parts. The following are several common applications of fasteners:
1. Screws: Used to connect parts such as sheet metal, wood, etc. and to achieve fixation.
2. nuts: mainly used together with bolts to connect and fix two parts.
3. Lock nuts: Used to secure connecting rods and bearings in high vibration environments.
4. studs: used in high temperature and high pressure environments, usually for connecting multiple parts.
5. bolts: used to connect parts with high load-bearing capacity, such as automobile engine covers. 6.
6. screws and nuts: used to fasten railings, handrails and other building structures.
7. washers: used to increase the fastener connection area, disperse the pressure generated by the fastener.
8. Steel wire rope: used to support machines such as cranes and elevators.
Fasteners have a wide range of applications, they have an important role in various industries such as construction, automotive, machinery, electronics and electrical appliances.
