Bolts are an important mechanical part that can be divided into many different types and are widely used. As the name suggests, double-ended bolts are threaded on both ends, and the middle part is a screw with different thicknesses. It is widely used in mining machinery, motorcycles, automobiles, large-span steel structures and large buildings. What is the main purpose of stud bolts?
Stud bolts
Stud bolts:
Bolts refer to screws with larger diameters, or heads, such as studs. In general, "double studs" are not called "double studs". The most common form of studs is threaded at both ends and a polished rod in the middle. The most typical use: where the anchor bolts or similar anchor bolts are located, thicker connections cannot be achieved with ordinary bolts.
The main purpose:
1, used in the main body for large equipment, the need to install accessories, such as sight glass, mechanical seal seat studs, deceleration racks and so on. At this time, the stud bolt is used, and one end is screwed into the main body. After the attachment is installed, the other end is put on a nut. Since the attachment is often disassembled, the thread may be worn or damaged, and replacement using the stud bolt is very convenient.
2, for the connector body is very thick, bolt length is very long, will use studs.
3, used to connect the thick plate and inconvenient to use hexagon bolt connection places, such as concrete roof trusses, roof girder suspension monorail suspension components.
Although the output of stud bolts in China is huge, it is relatively late in comparison with foreign countries. According to the survey, due to the lack of high value-added products, many developing countries have accepted the transfer of fasteners, which poses a challenge to the fastener industry in China. In recent years, there will be approximately 250 million yuan worth of fastener orders “escaped” each year. In China, the root cause of this status quo of China’s fastener companies lies in the lack of core technologies of local companies, and their inability to highlight their unique skills. Many enterprises have low scientific and technological inputs, weak technological development capabilities, backward technological processes, long lead times, and quality enhancements that lag behind the increase in volume. Enterprises have weak awareness of innovation strategies, insufficient capacity for independent innovation, and inadequate innovation system construction. In recent years, a large number of foreign fastener companies have entered the country, while China's fastener companies have both challenges and opportunities. Domestic fastener companies need to build brands, improve quality, ensure higher parts qualification rates, and continue to work toward the goal of zero defects.
