Bolts, nuts, rivets... These mechanical parts for fastening connections are called fasteners and are also known as "industrial rice" and are key components in the equipment manufacturing industry.
Fasteners are the most widely used mechanical foundation. A fastener is a general term for a type of mechanical part that is used to securely join two or more parts (or components) together. Fasteners are characterized by a wide variety of specifications, different performances, and a high degree of standardization, serialization, and generalization. Therefore, some types of fasteners with existing national standards are called standard fasteners, or simply It is a standard part.
At present, global fasteners are mainly used in the automotive industry, electronics industry and construction and maintenance industries. Among them, the automotive industry is the largest user, the demand accounted for about 23.2% of the total sales of fasteners; the second is the maintenance industry market and the construction industry, accounting for about 20% of the total sales of fasteners; the third is the electronics industry, accounting for The total sales of fasteners was 16.6%.
Non-standard fasteners refer to fasteners that do not need to correspond to the standard, that is, fasteners that do not have strict standard specifications, can be freely controlled and matched, usually by the customer to make specific requirements, and then by the fastener manufacturer Based on these data and information, general non-standard fasteners are more expensive to manufacture than standard fasteners. There are many types of non-standard fasteners, precisely because of the nature of non-standard fasteners, it is difficult to classify non-standard fasteners.
