Fasteners - Industrial Rice
A fastener is a general term for a type of mechanical component used to fasten two or more parts (or components) together into a whole. It is the most widely used mechanical basic component, widely used in industries such as automobiles, energy, electronics, electrical appliances, machinery, etc. Various fasteners can be seen in various mechanical equipment, vehicles, ships, railways, bridges, buildings, instruments and meters, etc.
According to product form classification, fasteners usually include the following 12 categories: bolts, bolts, screws, nuts, self tapping screws, wooden screws, washers, retaining rings, pins, rivets, welding nails, assembly parts and connecting pairs. This is also the traditional classification method for fasteners in China, which has always been used in the national standard. Among them, fasteners are divided into threaded fasteners (such as bolts, nuts, etc.) and non threaded fasteners (such as washers, retaining rings, pins, ordinary rivets, ring groove rivets, etc.) based on whether the geometric structure contains thread features. Thread fasteners refer to fasteners that are connected through threads. Thread fasteners can be further subdivided. Depending on the type of thread, thread fasteners are divided into metric thread fasteners, imperial unified thread fasteners, etc; According to the characteristics of the formed parent body, threaded fasteners are divided into three categories: externally threaded fasteners (such as bolts and studs), internally threaded fasteners (such as nuts, self-locking nuts, high locking nuts), and internally and externally threaded fasteners (such as threaded bushings); According to the position characteristics of threads on fasteners, externally threaded fasteners are divided into screws, bolts, and studs.
From valuing the development of automotive components to breaking through the bottleneck of core components
Fasteners are the most widely used mechanical basic components, known as the "rice of industry", and are one of the indispensable and important components in various industrial fields. According to the 15th to 14th Five Year Plans of China's national economy, the country's support policies for the fastener industry have undergone changes from "focusing on the development of automotive components" to "focusing on breaking through core basic components" and then to "filling the gaps in basic components".
During the period from the 15th Five Year Plan (2001-2005) to the 12th Five Year Plan (2011-2015), the country attached great importance to the development of the automotive industry and repeatedly proposed to improve the manufacturing level of key automotive components and achieve the autonomy of key components; Starting from the 13th Five Year Plan, breaking through the bottleneck of industrial core basic components has become a new development goal.
Future industry policy orientation - high-end and green
The direction of industrial restructuring in China's fastener industry is becoming increasingly clear, and in the future, the fastener industry will develop towards high-end and green development.
