The meaning and difference between fasteners and standard parts

What isFastenersMany people have the same question. As a layman could not be more clearly distinguished. So, let's understand the meaning and difference between fasteners and standard parts!

Fasteners and standard parts are two commonly used terms in the machinery industry, but many people cannot accurately distinguish between these two concepts and are easily confused.

Standard parts are commonly used parts and parts in mechanical manufacturing, which unify their varieties and size standards, and are large in quantity and suitable for mass production. In order to ensure the quality and versatility of these parts and components, the international technical standards and measures are adopted.

Standard products refer to parts and components manufactured in accordance with technical standards. There are many standard products with different performances and uses, and the degree of standardization, serialization and generalization is high. Such as bearings, gears, pipe joints, fasteners, etc.

Fastener is a component that realizes mechanical connection, and fastener refers to a general term for mechanical parts that have a connection or fixing effect. Fasteners manufactured according to technical standards are standard fasteners. When there are more than two parts, the parts that play a connecting or fixing role are fasteners, including bolts, nuts, screws, washers, rivets, pins, etc. Sometimes referred to as fasteners. Standard fasteners are an important category of standard parts.

Fasteners are generally widely used in various machinery, equipment, vehicles, ships, railways, bridges, buildings and structures, as well as tools, instruments and meters. There are all kinds of fasteners, and different fasteners are also very different, and there are many types. They have unique advantages in performance and use, but some are standardized and highly versatile fasteners.

Fasteners use more or a variety of metal rivets, depending on the region and country. For example, there are imperial, German, American, etc. Each metal rivet has specific requirements according to the product's specifications, dimensions and tolerances, as well as weight, performance and surface conditions. There are several specific technical requirements

Fasteners are widely used in mechanical basis. With China's accession to the WTO in 2001, it has become a major international trading country. Fasteners, as one of the products with large import and export volume in China, realize the cooperation with the international, and promote the Chinese fastener enterprises to the world. A large number of China's fastener products are exported to all countries in the world, and the fastener products of all countries in the world are also pouring into the Chinese market. It is of great practical and strategic significance to promote fastener enterprises to participate in international cooperation and competition. And the specific requirements for inspection, identification and packaging. Fasteners are now essentially standard. That is, the standard of the fastening class. According to the specifications, dimensions, tolerances, weight, performance, surface conditions, and marking methods of each specific fastener product, most of the standard products are fasteners, but the range of standard products is larger. So the scope of the two is basically the same.
