Precautions for the use of non-standard fasteners

  Сообщения и Комментарии  

Unstandard fasteners are non-standard fasteners. It is a kind of mechanical parts that are used for fastening and connection and are extremely widely used.
Non-standard fasteners include: bolts, studs, screws, nuts, washers, and pins. Locking or seizure often occurs on fasteners made of stainless steel, aluminum alloy and titanium alloy. These metal alloys have anti-corrosion properties. When the surface is damaged, a thin oxide layer is formed on the metal surface to prevent Further corrosion.
When stainless steel fasteners are locked, the pressure and heat generated between the teeth will destroy this oxide layer, causing blockage or shearing between the metal threads, and then adhesion. When this phenomenon continues, the stainless steel fasteners will be completely locked and can no longer be removed or continued to be locked. Usually this series of blocking, shearing, adhering, and locking actions occur in just a few seconds, so a correct understanding of the use of such fasteners can prevent this phenomenon.
From the fourth quarter of 2011 to the first half of 2012, due to the impact of the objective environment, the development speed of the unstandard fastener industry may slow down. The series of development policies introduced can promote the further development of the industry. And we must persist in innovation, adjustment and transformation, and promote the healthy and stable development of the fastener industry. The global fastener market exceeds US$50 billion, and China's total fastener output in 2012 is also expected to reach about 6.8 million tons. However, compared with manufacturing powerhouses such as the United States and Japan, there is still a big gap in my country's fastener industry. https://www.ydfastener.com/products/unstandard-fastener/
