Fastener introduction

Fasteners, also known as standard parts on the market, are a general term for a class of mechanical parts that are used to securely join two or more parts (or components) together. It is characterized by a wide variety of specifications, different performance uses, and the degree of standardization, serialization, and generalization is extremely high. Fasteners are the most widely used mechanical base parts and are in great demand.

Fasteners are a class of mechanical parts that are used for fastening connections and are extremely versatile. A wide variety of fasteners can be found on 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, different performance uses, and the degree of standardization, serialization, and generalization is also extremely high. Therefore, some types of fasteners with existing national standards are also referred to as standard fasteners, or simply as standard parts.

Fasteners include: bolts, studs, screws, nuts, washers, pins, retaining rings, studs, rivets, connecting pairs, wood screws, self-tapping screws.

Due to the specifications, dimensions, tolerances, weights, performance, surface conditions, marking methods, and specific requirements of inspection and inspection, marking and packaging for each specific fastener product, it is specified in several national (industry) standards. For example, there are English, German and American systems.

Fasteners are the most widely used mechanical foundation. As China joined the WTO in 2001 and entered the ranks of international trade powers. China's fastener products are exported to the world, and fastener products from all over the world are also pouring into the Chinese market. As one of the products with a large import and export volume in China, fasteners are in line with international standards, and it is of great significance to promote the Chinese fastener enterprises to the world and promote the full participation of fastener enterprises in international cooperation and competition. Strategic significance.
