threaded studs Tighten the connection
A general term for a class of mechanical parts used to fasten two or more parts (or components) into a unit.
Fasteners are a class of mechanical parts that are used for fastening connections and are widely used. Various types of fasteners can be seen in a variety of machinery, equipment, vehicles, ships, railways, bridges, buildings, structures, tools, instruments, meters and supplies. It is characterized by a wide variety of specifications, performance purposes vary, and standardization, serialization, generalization of the species is also very high. Therefore, some people have a national standard of a class of fasteners called standard fasteners, or simply referred to as standard parts.
Fasteners include: bolts, studs, screws, nuts, washers, pins
Fasteners, also known as standard parts on the market. Is a fastening connection with a class of mechanical parts, the application is extremely wide. Fastener features: variety specifications, performance uses vary, and standardization, serialization, generalization of the degree of high. Therefore, some people have the country (industry) standard class of fasteners called standard fasteners, referred to as standard parts.
Due to the specifications, size, tolerances, weight, performance, surface conditions, marking methods, and acceptance requirements for inspection, marking and packaging of each specific fastener product, it is specified in several national (industry) standards , Such as British, German and American.
Fasteners are the most widely used mechanical foundation pieces. With China's accession to the WTO in 2001 and entered the ranks of international trade power. China's fasteners a large number of products exported to countries around the world, the world's fastener products are also constantly influx of the Chinese market. Fasteners as one of China's large imports and exports of products, to achieve international standards, to promote China's fastener enterprises to the world, to promote the full participation of fastener enterprises in international cooperation and competition, have an important display and Strategic significance.
A fastener is a generic term for a class of mechanical parts that are used when two or more parts (or components) are fastened together. Also known as standard parts on the market.
It usually includes the following 12 categories of parts:
1. Bolts: A fastener consisting of a head and a screw (with an external thread) is required to be fitted with a nut for fastening the connection of two parts with through holes. This type of connection is bolted. If you remove the nut from the bolt, there are two parts can be separated, so the bolt connection is a detachable connection.
2. A type of fastener that has no head and only the ends that are threaded at both ends. When connected, it must be screwed into the part with internal screw holes, the other end through the part with the through hole, and then screw the nut, even if the two parts are tightly connected to see the whole. This type of connection is called a stud connection and is a detachable connection. Mainly used for one of the connected parts of a larger thickness, requiring a compact structure, or because of frequent demolition, should not be bolted to the occasion.
